Fractal Design Integra R2 750W 80 PLUS Bronze Power Supply Review - Tweaktown

Quote:

It is without a doubt that Fractal Design intends for the Integra R2 to be utilized for those seeking a budget unit in a mid-range computer. In that essence, they have succeeded very well. The Integra R2 750W power supply is certainly without some of the frills that we have come to expect out of the higher end units such as modular cabling and Over Temperature Protection, but by doing so they manage to keep the cost down significantly.
Keeping the cost down isn't always that hard to do. Many simply cut the quality of their product and the performance of the unit readily reflects those decisions. This isn't the case with the Integra R2. There have been a few cuts to quality along the way, but they are so minor that they will never be known. Sure, the voltage regulation and DC output quality aren't the most superb on the market, but they are very well within specifications and we have seen many other "quality" units that have performed on the same level that the Integra R2 has shown itself to be capable of. We're fairly confident that it is simply the choice in Taiwanese capacitors that are keeping the unit from providing some better numbers.

It is probably the same choice that provides the reasoning behind the three year warranty, which is one of the few things that we really have to complain about. It seems to go hand in hand that every time we find Taiwanese capacitors that we also find a shorter than average warranty for the unit and it is not a coincidence.

AeroCool Introduces GT Power Supply Series to the European Market

Brand new GT series aims for ambitious gamers and enthusiasts, coming with total of eight different models starting with 500 Watts and ending with 1.050 Watts. The acronym "GT" is coming from the Italian words „Gran Turismo", which stand for high-performance luxurious racing cars, built for long distance racing. Aerocool engineers too the challenge seriously both for designing the exterior as well as the interior.

New GT Series is split in two different model-ranges where one is certified with 80PLUS Bronze and the other with 80 PLUS Gold! Hence assures an efficiency of at least 85% respectively 90%. Aerocool achieved this by using two VRM modules, which are using one choke contrary to commonly used designs. This allows the two 12 Volts rails to have a maximum voltage deviation of only 3%, which is lower compared to the required 5% by Intel's specifications. Aerocool aims to deliver high efficiency and stability especially during long load sessions with its new GT PSU Series.

Aerocool GT power supplies exterior catches attention due to the fresh and stylish design. Entry-level models with 80PLUS Bronze specification are using black and red color matching. High-end models with 80PLUS Gold specification can be identified by the black and white color finish. In addition, the whole chassis was refined by round shape alongside with a mesh-grid to deliver an outstanding design far from standardon-market power supply units. All GT PSUs are equipped with a white 13,9 centimeter fan to further unify the design. Thanks to the big size of the built-in fan and the intelligent fan controller, the GT power supply units are ableto operate very silently at all time and adjust fan speed according to the actual load. MTBF of the Aerocool GT power supply units is stated with 120.000 hours to assure long and uninterrupted gaming sessions.

To further comply with every users requirement, GT PSU series are available as a standard version with attached connection cables as well as a smart modular cable version for more convenient cable management inside the PC chassis. Versions with the smart modular cables can be identified by the letter "S" in the model name. In addition all GT PSU support both the ATX12V 2.3 as well as the EPS12V 2.92 standards and offer enough connectors for the required PC components. Furthermore SLI and CrossFireX are supported, allowing enthusiasts and gamers to build even more powerful systems. In the case of the smart modular cables version ("S" models) black colored flat cables are being used, allowing easier cable management. Other models are utilizing cables covered with mesh sleeves to assure a better airflow inside the chassis.

Another highlight is the low power consumption in standby mode thanks to the compliance to ErP Direction 2013. To ensure safe operation,all Aerocool GT power supply units are supporting the Over Current(OCP), Over Voltage(OVP), Over Power(OPP), Over Temperature(OTP), Under Voltage(UVP), Short-Circuit (SCP) and Surge/Inrush current protections(SIP) protections.

Aerocool GT PSU series is divided into three groups where the GT-500 and GT-700 power supply units come with attached cables, red finish as well as 80PLUS Bronze specification. Second group includes the GT-500S, GT-700S and GT-1050S power supply units with smart modular cables, 80PLUS Bronze and red color. Last group is made of the high-end models GT-500SG, GT-700SG and GT-1050SG supporting smart modular cables, 80PLUS Gold as well as white color finish. All models are available on the European market as of today for the following MSRPs:

GT 500W: 58,00 EUR
GT 700W: 75,75 EUR
Gt-S 500w: 64,65 EUR
GT-S700w: 80,69 EUR

Cougar GX 800W Power Supply Review - kitguru

Quote:

The Cougar GX 800W is a capable power supply that fails to impress in any key area but when considered as a ‘sum of its parts’ is actually deserving of a reserved recommendation.
The appearance of the GX 800W is certainly going to split opinion, we know from past experiences that some of the enthusiast user base loathe gold panels as they can clash against specific colours when featured in a windowed case.
The quality of finish is reasonably good, although the paintwork is easily damaged and a lot of handling care will be needed if the unit is to maintain a pristine appearance during multiple build phases.
The modular cabling looks great and there are no shortage of cables for an 800W rated unit. We would like to see this HEC design evolving, with a lower reliance on the amount of hardwired cables. We do like the flat, branded ribbon modular cables however, they really do look fantastic.
Cougar supply 4 x PCI E 6+2 pin cables with this unit, which is enough to power a high end dual card Crossfire or SLI system. We would recommend you aim for a 1000W unit if you want to power more than two high end graphics cards anyway.
Technically the GX 800W is pretty good and HEC are using a high grade 105c Panasonic capacitor in the primary stage. The GX 800W delivers decent load regulation and passed our cross loading test without a problem. Ripple suppression isn’t the best we have seen in recent months however and our test unit recorded a 50mV result from the +3.3V output, which is borderline to a fail. We wouldn’t expect any problems long term, but it is worth noting.
The large fan in this unit cools the components well although in the last 200W of total output it can spin up noticeably, generating a reasonable amount of noise. It is never that intrusive, but if you need to push more than 600W on a regular basis you may want to look at another unit. HEC really could have balanced the fan speed a little better, opting for a slightly quieter profile.
Internal build quality is quite good, although not at the same level as the Flextronics or Seasonic designs we have seen in recent months. It falls short of the top grade.
The price in the United Kingdom as we go to publication is around £140 inc vat, we found it on Amazon for £137.99 inc vat. Cougar will really have a problem selling the GX 800W when you can pick up superior alternatives such as the Corsair AX850W for only £147.42 inc vat or Seasonic X Series 850W for £149.99 inc vat. We think this is really is going to be a tough sell for Cougar in the UK.
Pros:

Good all round build.
brightly coloured.
quality cables.
can deliver over 820W before shutting down.

Cons:

paintwork could be better.
ripple issues on +3.3V output.
quite expensive.
not fully modular.
Fan profile is quite aggressive at higher load.

Affordable Gold from Seasonic: G-360 and G-550 Power Supply Units Review - xbitlabs

Quote:

The junior model of Seasonic's new Gold-certified PSUs, SSR-360GP, doesn't seem to have any alternatives if you need a high-efficiency ATX power supply with a wattage rating of below 400 watts. We can't recall any other Gold-certified PSU with similar specs whereas fan-less models of that wattage cost almost twice as much. That said, the 360W PSU is going to be sufficient for a rather advanced PC configuration with a top-end CPU, a rather fast graphics card and a few HDDs.
The higher-wattage models of the series are priced comparably with Cooler Master’s Silent Pro Gold PSUs of similar wattage, which are based on an Enhance platform. The Seasonic PSUs are louder at high loads but quieter at low and medium ones. They are also better in terms of output voltage ripple.
Compared to other Gold-certified products, the Seasonic G series is only a little more expensive than the FSP Aurum (and Aurum-based PSUs of other brands, like Thermaltake's Toughpower GOLD). However, the FSP Aurum is inferior across a number of parameters such as output voltage ripple, acoustic comfort (at any load) and voltage stability.
Thus, Seasonic has come up with a very good series of affordable Gold-certified PSUs. With their price/specs combination, they have only one competitor, Cooler Master’s Silent Pro Gold. However, the two series overlap but partially (the Silent Pro Gold begins at 550 watts whereas the Seasonic G series ends at 650 watts), so the Seasonic G series has no real alternative at the lower wattages.
Highs:

Comparable to their more advanced X series counterparts in voltage stability and efficiency
Low output voltage ripple
Very quiet at low and medium loads
Good selection of cables and connectors
Adequate load capacity of each power rail
Low price (for an 80 PLUS Gold product)

Lows:

Noisy fan at high loads
Rather short CPU power cable

nJoy Rogue 600RGE Review -pcmhz

Quote:

Sursa celor de la nJoy a plecat din redacţia PCMHZ lăsând în urmă ceva ce s-ar rezuma foarte pe scurt în "cinstită". nJoy este un brand românesc relativ nou, patriotismul trebuie însă privit în acest caz doar ca un element terţiar dar chiar şi aşa, produsul lor este unul ce respectă în cea mai mare parte cerinţele sectorului de piaţă căruia i se adresează.
Cu un preţ recomandat de producător undeva la 269 lei, sursa de alimentare nJoy Rogue 600RGE este pe aceaşi palier de preţuri cu sursele de calitate din zona de puteri 400W-500W. Faptul că poate susţine configuraţii destul de pretenţioase o recomandă celor ce din considerente tehnice (putere) dar şi de preţ (nu toţi îşi permit să cheltuie 4-500 lei pentru o sursă de 600W) au nevoie de acei 600W. Nouă ne-au plăcut aspectul exterior (subiectiv), cablurile lungi separate cu meşe, paleta completă de conectori şi operarea silenţioasă.
Părţile negative sunt puţine şi se învârt mai ales pe zona filtrării şi a monitorizării/compensării voltajelor la output, lipsa unor dotări avansate specifice oferind pe hârtie (grafice) valori gri, comportamentul în cazul utilizării reale fiind însă unul neaşteptat de bun. Iar dacă totuşi apar probleme, garanţia de 24 luni le rezolvă.

Fractal Design Tesla R2 650 W Power Supply Review - Hardwaresecrets

Quote:

The Fractal Design Tesla R2 650 W proved to be a very good mainstream power supply with the 80 Plus certification, with an excellent price tag and, therefore, a recommended unit.
It is based on the same platform as the Rosewill FORTRESS-650. Rosewill’s version, however, uses slightly different components inside. Of note for the average user is the use of better capacitors, manufactured in Japan by Chemi-Con, and a total of four video card power connectors instead of only two. The model from Rosewill is also USD 10 cheaper.

Cougar PowerX 550W Power Supply Review Review - Legit Reviews

Quote:

The Cougar PowerX 550W power supply obviously is a product designed to entice users into upgrading from a cheap unit of unknown (and, usually, extremely poor) quality to one of acceptable quality and performance standards. Considering that the MSRP of the power supply is just $69.99 and that the actual retail price usually is quite lower than the MSRP, the PowerX 550W might actually be a very good deal for casual users and gamers on a very tight budget. On the other hand however, the saying "you get what you pay for" fits perfectly in this case. Cougar designed the PowerX 550W unit to be a quality product for those on a tight budget and a quality product it is; well designed and made, with proper protection circuitry and backed up with a 3 year warranty. But that is where the magic ends, as the only overall performance of the PowerX 550W power supply is nothing more than acceptable.

We believe that the greatest shortcoming of the PowerX 550W was its middling electrical performance, as advanced users will primarily aim for high performance over anything else, even if they are strongly limited by their monetary budgets. The PowerX 550W meets its 80Plus Bronze efficiency certification but the voltage regulation is middling and the ripple suppression is rather poor. We realize that this power supply likely costs less than the keyboard of an advanced gamer and thus we expected no miracles from it; however, we honestly believe that Cougar could have done more than a little better on the electrical performance, which would make the PowerX 550W power supply a very competitive product. Thankfully, at least the acoustics performance of the PowerX 550W is very good, therefore it should greatly appeal to users who primarily aim towards quiet computing.
Aesthetically, this is no modular power supply but Cougar certainly placed some effort into making it visually attractive. The company sleeved all of the cables down to the last connector, embossed the chassis and installed a bronze-colored cover. These are usually more than enough for a power supply of this price range. We can only argue that the bronze-colored cover might not be such a good idea, not everybody likes fancy colors and colorful combinations.
Legit bottom line: The Cougar PowerX 550W power supply is a reliable, well-made product for advanced users and gamers on a tight budget. Its middling performance however does not make it particularly competitive, unless the actual retail price ends up significantly lower than the $69.99 MSRP that we have been informed of by Cougar.

Thermaltake Toughpower XT Platinum 1275W Review - PureOverclock

Quote:

Thermaltake has done a fine job with the Toughpower XT Platinum 1275W, improving on its predecessors and offering consumers a very complete package here. The features here are excellent, and the S.P.T lighting indicators are innovative and will be very helpful, particularly for end users that may not be very knowledgeable about computer systems and want to monitor their rig.
In terms of aesthetics, it’s also an attractive power supply, though a bit over the top in terms of labels, which clash a bit with the stealthy black styling otherwise. Functionally, the unit has a scratch and fingerprint-resistant coating in a textured matte black finish. This gives a a simple and elegant style that will fit into just about any system build.
From a features standpoint, the unit is 80PLUS Platinum certified, which is at the top end of power efficiency these days. The hardwired cables lengths could be a couple inches longer, and could be a potential nuisance for anyone who’s very picky about cabling inside a full tower. However, as we know, looks and features are only a small part of the equation with power supplies, as features and performance are where things are decided.

In terms of performance, the Toughpower XT Platinum 1275W finished rather well, with nominal movement on the rails in our voltage regulation testing, while the ripple results were also very good. Not quite the best we’ve seen, but well within specification. The 80PLUS Platinum efficiency is a boon to those looking for “green” solutions, though it could be argued that if you need a 1275W power supply then you’re not exactly energy-frugal to begin with.
Priced around $290, this unit is a bit on the expensive side against similar competitors, though you do get a very solid power supply here, with little worry about quality or performance. If you want a top tier power supply that can provide enough juice to run a behemoth computer system, then the Thermaltake Toughpower XT Platinum 1275W is a great option.

Cougar GX-S 500W - jonnyguru

Quote:

Cougar's little 80 Plus Gold GX-S unit has a lot going for it. It's very stable in regulation, it's quiet, it runs cool, and holds the ripple well in check. It does have a few edges that could use some sanding down, like that little rise time and overshoot spike thing we saw in the power-up overshoot transient testing, but in general this is a rather good unit for both Cougar and their partner in Andyson. I like it. Now, if it can hit the market at a competitive price, Cougar will be all set.
The Good:

very good voltage stability
very good to excellent ripple suppression
no problems meeting Gold efficiency
shallow housing depth
love that fan

The Bad:

the unit was a little loosey goosey with the overshoot transient tests - all three of them

The Mediocre:

MSRP may mean not so great a value
I'm out of energy drink... meteoric caffeine crash in 3... 2... 1...

Performance: 8
Functionality: 8,5

Rosewill Tachyon 1000W - jonnyguru

Quote:

With this unit, Rosewill again shows us how serious they are about competing in today's power supply market. Among all the 80 Plus Platinum designs that I know of, it's really a two company show at the thousand watt level as for who has the best design. This unit uses one of those designs. There's nothing more I can say about it... this power supply is absolutely worth putting your money on.
The Good:

very stable voltages
gave us Platinum efficiency both hot and cold
outstanding ripple suppression
semi fanless mode works well

The Bad:

too many hardwired cables yet
fan made me worry about long term health

The Mediocre:

I have to spend how much on a good DSLR lens?

Silverstone Strider Gold ST55F-G 550w - jonnyguru

Quote:

The first time I saw the platform used by this unit, it was somewhat of a disappointment. It didn't hit its 80 Plus Gold target, ripple suppression wasn't quite good enough, and it wasn't quite as competitive as it needed to be in today's market. The same is not true for this version. The 550W model is only one small step away from being a truly excellent unit indeed, and I am quite happy to add it to my list of recommended units. If it had slightly better ripple suppression, Seasonic would be mighty nervous right now. At any rate, you aren't going to find anything else fully modular at this power level in such a shallow housing. If such a unit exists, I don't know about it. That might make all the difference for you folks with shallow power supply requirements.
The Good:

shallow housing
very good voltage stability
very good ripple control at 12V and 5V
fully modular
excellent documentation

The Bad:

3.3V ripple could use a little improvement

The Mediocre:

not one single thing

Performance: 8,5

PC Power&Cooling Silencer Mk III 850W – Test practic - lab501

Quote:

Inca un final de articol PC Power & Cooling, inca o concluzie polarizanta. Noile Silencer Mk III sunt doua surse de top, ca sa fie totul clar de la inceput, pentru ca in ceea ce priveste electronica nu s-a facut rabat de la calitate sau performanta. Pentru aproximativ jumatate din pret puteti cumpara o sursa aproape identica cu flagship-ul de 1200W, doar mai slab dimensionata. Si din fericire, acest lucru e adevarat.
Pe pagina anterioara puteti vedea cat de lejer se descurca modelul de 850W cu o configuratie super high-end triple-GPU. Nu a transpirat deloc, voltajele au ramas practic neschimbate, iar rezerva de putere este vasta. La nevoie puteti folosi inca 250W peste cei 850W garantati de producator, desi nu recomand niciodata aceasta practica. Si in ciuda performantelor, Silencer Mk III este o bestie usor de domesticit. Modul semi-fanless face din sursa PCP&C una potrivita atat pentru daily-use cat si pentru benchmarking. Sincer sa fiu, acesta s-ar putea sa fie cel mai important feature al sursei…
… pentru ca ventilatorul nu se ridica la nivelul impus de restul componentelor. Zgomotul de motor ar fi usor de auzit intr-o incapere linistita. Sper ca exemplarul nostru a fost problematic iar acest minus nu va caracteriza toate sursele Silencer Mk III de 750W sau de 850W, pentru ca nu mi-ar mai ramane nimic de reprosat.
Pretul recomandat este de $150 pentru modelul de 750W si $170 pentru cel de 850W. Judecand dupa pretul modelului de 600W, care la noi costa in jur de 370 de lei iar in S.U.A. $100, noile modele ar trebui sa ajunga pe raft la 550, respectiv 630 de lei. Cand si daca vor ajunge la noi in tara, aceste preturi le-ar propulsa in topul recomandarilor mele pentru cei care cauta o sursa de putere mare insa nu vor chiar sa scoata banii de sub saltea. E foarte simplu, pentru banii platiti primesti o sursa mai scumpa.

PC Power & Cooling MK III Silencer 750 Review - Guru3D

Quote:

This is the second Mk III we tested and it feels good to have a P&C power supply on the test bench again. I am very impressed with it and this conclusion will be close to what you have seen with the 1200 Watt model, aside from the capacity, it's the same stuff really. The work done on this unit is a little substandard, a very distinct feature is the modular looks with the pin style modular connectors, very impressive but we remain to state that there is a flaw with the design. Let me explain:
The male connectors are placed in the PSU, and the female connectors on the cabling. Now the PSU side modular connector have been protected with a plastic cap, but if you have sweaty hands and are fooling around in the PSU area, god forbid you touch the male connectors. The connectors would have been reversed, female on the PSU and male on the cables. Then again, leave the plastic caps on and make sure you are aware of it and you'll be fine of course. Now admittedly, it does look cool. So just be careful and try to remember what I just stated okay ?
So overall it once again was a pleasure to test the unit. It obviously had no issues whatsoever that we could detect with whatever we threw at it, we reached just over 730 Watt which is close to the theoretical maximum of this PSU. I say theoretical as I dare to state that this PSU would even work at a 900 Watt power draw, the build complexity and choice in components just is excellent. While passing 700 Watt load we the power efficiency remains great, actually closing in at the level of Platinum tested models. At that high load level you'd expect power consumption to get worse, well slightly worse, but that was not the case and makes the Silencer Mk III 750Watt a class in its own.

Stability wise we have very little to complain about we loaded it load up-to 733 Watt and voltages remained drop dead synchronized. But we'll trust that some other reviews will show some ripple tests yet have no doubt the product will come out totally clean. Fantastic is obviously the massive single +12V rail, it has just so much power to handle multiple heavy duty graphics cards. I mean 62AMPs. Bare in mind that one graphics card uses 15A on average these days so yeah, you got some spare.
But lets round things up. The PSU is very efficient, has good looks, though white is a bit of a dangerous color for most dark chassis, then it's modular, is stable, comes with all dark cabling and connectors and then we have to acknowledge it's silent as well. So it's all good really. Pricing might be a bit steep for some of you but do bare in mind that this is a sheer quality power supply. OCZ will give you a 7 year warranty with this product, and yea ... that does make up a lot.

Remember, a PSU is the most efficient at 50% load, making this power supply perform superb (in efficiency) at 350 Watt. Up-to that point it's fan-less as well. 350 Watt is roughly the equivalent a Z77 motherboard, with a Radeon HD 7970 or GeForce GTX 680 at work in a nice gaming spree. So that's the point where it is drop dead efficient. All factors combined with that nice capacity rich 12V rail, the modular connectors, the sheer design and that 7-year warranty makes the Silencer Mk III 750 a pretty intriguing power supply to own. Definitely recommended if you are a mainstream to enthusiast PC user that needs a little extra with nice looks and the craving need for a quality power supply.

PC P&C managed to close the gap between its high-end Silencer MK3 1200 W flagship and the lower capacity-models of the series by introducing the MK3S750 and MK3S850 units. Today's review sample, the MK3S750, managed to achieve a pretty high overall performance by registering high efficiency throughout its entire operational range, tight voltage regulation at +12V, very good ripple suppression on all rails, and a dead-silent operation at low loads while its semi-fanless operation mode is engaged, and although its MSRP looks kind of high, setting it very close to the tough Platinum competition, the final retail price is usually a few bucks lower, which means the MK3S750 will probably achieve an even higher price/performance ratio.
Our only objection is that it doesn't have an MOV in its transient filtering stage, something that applies to almost all Super Flower platforms we tested so far, but you can connect the PSU to a surge protector or UPS to solve this problem. Also, voltage regulation on the minor rails could be better (this platform usually achieves way better results on its minor rails, so we may have just hit a poor sample), but there is a reason these rails are called "minor". What matters most is the performance of the +12V rail and it did fine.

The smaller, Gold efficiency, Silencer unit does, to conclude, look to be the right choice if you desperately want a white-colored PSU and don't need a 1.2 kW monster, especially if you add to all the above its seven-year warranty, since that makes the Silencer MK3 750W a great-looking deal despite its somewhat high MSRP.

PC Power & Cooling Silencer MK III 750W Review - Kitguru

Quote:

The PC Power & Cooling Silencer MK III 750W is unquestionably an excellent power supply which will reinforce the brand name within the enthusiast sector. The bright white appearance may not suit everyone but there is no doubt that the build quality is deserving of some praise.
The new XLR style connectors are a fantastic feature which really improve on the plastic clip attachment system incorporated by competitors. The snug fit will ensure the best connection possible and they will be impossible to dislodge accidentally.
Technically, the PC Power & Cooling Silencer MK III 750W is a proficient design which exhibits no real weakness. It is true that flagship products from Corsair and Seasonic deliver higher efficiency readings and better ripple suppression, but these are currently the best on the market.
Load regulation from the MK III 750W is very good, and the unit passed our cross loading test without a hitch. We managed to get over 820W out of it before the protection circuitry would shut it down.
The large fan manages to emit very low noise, even when loaded heavily above 500W. This power supply may be overkill for a media center but the passive fan profiling means it is ideal for noise critical environments.
We have no UK pricing yet for this power supply, but OCZ informed us that the 850W unit will cost $169.99 and the 750W reviewed today $149.99. It is difficult to accurately guess how this will translate between America and Britain, but the Seasonic X Series 750W unit is currently available for £124.99 inc vat so the MK III 750W will need to be closely matched if OCZ want to claim sales.
We can certainly recommend the PC Power & Cooling Silencer MK III 750W, but it does face some stiff competition from the likes of Seasonic (X Series 750W) and Corsair (AX760 & AX760i).
Pros:

solid technical design.
XLR modular connectors are a move forward.
high efficiency.
good ripple suppression.
quiet.
7 year warranty.

Cons:

facing a lot of competition from the market leaders.

Who's Who In Power Supplies, 2013: Brands Vs. Manufacturers - tomshardware

Quote:

A PSU is not necessarily bad because it is cheap. But the lower the price, the more you'll likely have to skimp on safety and performance features. A high-quality PSU contains more expensive components. If you buy cheap, you might have to buy twice--or more.
A PSU is not automatically inferior because it was made by a contractor with which you aren't familiar. These companies make all kinds of products, from luxury brands to pure garbage. Again, it's a question of hitting different production targets. Is the product built for quality or aggressive cost reduction? The responsibility always lies with the buyer to recognize and reject products that are obviously unsuitable.
In the light of the previously presented tables of manufacturers, some quality issues, such as those seen with Be Quiet's P6 series, present an additional aspect to consider. We can also see that companies like Super Flower are often underestimated because they are not seen and accepted as the large manufacturer, which in fact they are.

Fortron's channel brand FSP unveiled its Aurum 92+ line of modular PSUs. The 80 Plus Platinum compliant power-boxes will initially ship in two mid-range capacities, 550W (PT-550M) and 650W (PT-650M). The two feature Fortron's innovative FSPMIA-IC, a single chip that integrates various voltage regulation and protection functions, minimizing clutter on the PCB. Both models use a quad-rail technology, with four 18A +12V rails. The company's HybridSynergy technology allows load to be spread across the four rails. Most common protection features are covered. The two feature partially modular cabling, with the 24-pin ATX, 8-pin EPS, and a PCIe connector being fixed, while the SATA/Molex connectors and a second set of PCIe cables are modular. The two will reach stores some time in February.

Fractal Design Newton R3 600W Power Supply Review - ThinkComputers

Quote:

The Newton is the first power supply we have taken a look at from Fractal Design and I have to say I am very impressed. With the Newton Fractal Design wants you to know you are receiving a premium product and from unboxing to installation the power supply gives you that feeling.

When it comes down to performance the Newton R3 600W did great. Voltage regulation on both the 12V and 5V rails was under 1% and the 3.3v rail was just over 1%. That means you are going to have very stable power delivery to your components. Also this power supply is 80PLUS Platinum certified so you are going to have 92% efficiency at 50% load and 89% efficiency at 100% load.
Since this power supply is semi-modular you are only going to use the cables you need. This means less cables laying around obstructing airflow inside of your case. The flat cabling design on the modular cables makes them very easy to route and mount in permanent locations. The cables comes in a very nice cable kit. This kit can be rolled up and easily stored away or put in your LAN bag. When you open the cable kit up all of the cables are in labeled spots, which even tell you the length of the power supply. These small details are things I really like about this power supply!
Power supply designs are really nothing to write home about, but I really like the Fractal Design logo on the side of the unit and the embossed snowflake on the top. If you happen to have a case that shows your power supply I would definitely want to show this power supply off! I also like how quiet this power supply is. Remember the fan is semi-passive, which means it only turns on when the power supply reaches a certain temperature.

Pros:
- Good performance
- Semi modular
- 80PLUS Platinum certified
- Attention to detail in packaging & design
- 5 year warranty
Cons:
- Availability

PC Power & Cooling Silencer Mk III 850-Watt 80 PLUS Gold Power Supply Review - Tweaktown

Quote:

As we have seen from the past, the Silencer Mk III series of power supplies is a solid lineup. The problem until today is that it has been for those who were seeking entry level or full on enthusiast grade power supplies with nothing in between. The introduction of the Silencer Mk III 750W and 850W power supplies fills the void very nicely.

Looking at the power supply from a performance perspective, one can't argue that the Silencer Mk III produces solid results and provides just what power users and entry level enthusiasts seek. Voltage regulation is great all the way around, staying within 2% of specifications on both the 12V and 5V rails and barely stepping into 3% with the 3.3V rails. Ripple suppression is fantastic as well and never manages to go above 33mV at full load. The efficiency delivered is just as promised as well. While there may be more efficient models on the market, 80 PLUS Platinum units tend to run a bit more expensive, too.

It is nice to see that the issue of having such low output available on the 3.3V and 5V rails for the 1200W model has been addressed. We'd still like to see a few things addressed such as the lack of OTP and the fan mode switch being labeled, but no unit is completely perfect and these two issues are part of the drawbacks of the Silencer Mk III series.

Pricing for the Silencer Mk III 850W puts it very much in the middle of the pack for 80 PLUS Gold rated units which is right where this unit should sit. It is very much a strong jack of all trades and master of none. Aside from color, it doesn't have much that makes it stand out from what is on the market. That is both a curse and a blessing as it makes the choice even more difficult for the end-user, but more to choose from to suit their individual needs. Rest assured that if you do choose the PC Power & Cooling Silencer Mk III 850W power supply, you won't be disappointed.

PC Power and Cooling Silencer Mk.III 850W Power Supply Review - HardwareHeaven

Quote:

As was the case with the previous Silencer Mk.3's that we have reviewed PC Power and Cooling create a great first impression with this PSU. The packaging feels decent quality and the PSU is protected well inside by various materials. Once it is removed from the protection the PSU continues to impress with a good quality finish and solid feeling chassis. The white/black colour scheme really stands out and we love the modular connectors which are used here, really making for a unit which has visual appeal. If we had to be really picky the lack of a mixed cable (featuring Molex and SATA connectors on one wire) is disappointing but that's really the only notable "issue" and something we have noted before on this range.
To be clear, mixed cables are a huge bonus as those annoying components which require a single Molex in modern systems can be connected without adding in a full cable of Molex. Just use the one on the mixed cable that is already installed for SATA drives... much more tidy.

Anyway, inside the PSU we find quality branded parts and some nice little touches such as a decent amount of separators, ties and adhesive which show care was taken with the assembly. This good level of build quality is backed up by some decent performance offering stable voltages, gold level efficiency and good temperatures. As before we also very much liked the ability to run fanless up to 50% load which means many systems will have a "fanless" PSU under normal desktop conditions.

Rosewill Tachyon 750W Modular Power Supply Review - BCC Hardware

Quote:

The Rosewill Tachyon 750W 80 PLUS Platinum Power Supply is the mid-range unit in Rosewill's Tachyon line and it performs like a champ. There is a bigger 1000W version of this unit that is based off the same design and is geared towards those with massive systems. The reality is that the 750W version we looked at today is more than adequate for a Core i7-3770K with a couple of high-end graphics cards.
Our test system never even made this sweat until we added an extra load on this unit. As it stands, the Tachyon 750W unit is solid enough to run most hardware without any issues. To stress out the 12v line, we plugged in a heavy 12v load and watched the power draw climb. It pushes out a lot of watts and has proven to be solid, stable and run quite cool. The hottest internal component reached 48°C when testing in our office with an ambient temperature of 23°C. It handled its rated load and even peaked over 780W without issues.
There really isn't any downside to this Power Supply. It is nice and quiet. It has a great finish and earns a Platinum rating by being at least 92% efficient. It's a great power supply that deserves some consideration for your next build.
Pros:

Very low electrical noise
Nice design and layout
Rock solid performance at maximum rated load
Fan is quiet and cools well
Lots of connectors for just about any system
80 PLUS Platinum

Cons:

At $179.99 for a 750W PSU - It's not cheap

Lepa G1600 PSU review - Guru3D

Quote:

The Aesthetics

The looks and feel then, for a PSU in the 1600~1700 Watt ranges you expect to receive the Big Ben amongst PSUs, and that just isn't the case. The PSU is only 3CM longer than your typical ATX based PSU and that allows for it to be installed in pretty much any modern chassis.
The looks don't suck either, the dark matter grey outside finish resembles Enermax alright, alongside the gold font it just is a very nice product to look at. The cables are done right in a dark black sleeved coating. Unfortunately the connectors themselves are not black, the PCIe graphics connectors are red, and that's not what we want in 2013. A minor remark though. The added modular benefit obviously is very clean looking wiring for that cool looking finish. The cables themselves are sturdy and a bit hard to bend though, you could be fighting with that a little during installation.
Obviously, Modular designs are the way to go. Anno 2013 it seems it's not hindering efficiency any longer. You use what you need in terms of wiring, keeping the innards clean and tidy, plain and simple. And overall the G1600 is a nice looking PSU, merely a small hint longer than your typical ATX sized PSU.
Efficiency

Combined with the Gold factor -- the certified model at 90% efficiency at 50% load -- the PSU seems to be behaving quite well. Our tests show that the PSU positions itself where it needs to be and it was testimony of a grand PSU. Remember though that the best efficiency of a PSU is always at 50% load. But even with your PC in IDLE you are looking at 88% efficiency. Put it under roughly 50% load and with 230V it even creeps dangerously close towards Platinum levels.
The Money

Here's the real shocking thing, you'd expect a PSU of this class to be really expensive, at least 350 EUR right? Well, a quick peek in some EU price watch engines lists this product for 255 EUR already, and that's including VAT. We think that is just a terrific price for a great looking PSU that is fully modular and rated at 1600 Watt capacity. For those that wonder, Sirtec seems to be the OEM behind the product. Warranty wise again we can't complain ... you receive 5 Years Manufacturer Warranty.

Final Words

The LEPA G1600 PSU (MA-EU model) surprised me in many ways, for its wattage capacity it remains very efficient, it has good looks, is modular, is stable, comes with all dark sleeved cabling. Then LEPA tops it off with a five year warranty. The 1500+ Watt PSU market isn't very crowded and for reason, only very few will actually need a PSU of this grandeur, it's for the enthusiasts, pro-overclockers, multi-GPU addicts and the guys that run 2-way processors on their motherboard. These guys will need to pay top dollar though. But good quality, efficient, very stable and affordable remain the keywords for this product here. I mean we spotted it for 255 EUR ... that is staggering really.

Aerocool GT-SG 700W Review - TPU

Quote:

The Aerocool GT-700SG has an MSRP of 121.5 EUR and wasn't available in the USA at the time of the review.

Resilient to high operating temperatures
Great ripple suppression
Efficient
All rails within 3% voltage regulation
Silent enough operation throughout the low to middle load range
Stealth (and flat) modular cables
Nice looks

Price is on the high side
12V rail turn-on transient performance
Small hold-up time
Warranty period could be longer

The new Aerocool GT-700SG definitely has the looks, but does it have the appropriate performance to face the competition? Well, according to the results of all the tests I conducted, I can surely say that it does. Voltage regulation on all rails may not be super tight but is still within 3%, ripple suppression is great, and its efficiency is a little above Gold levels. Also, the output noise of the unit's fan is not so high, at least under normal operating conditions and low to middle loads. However, I would prefer the use of a double ball-bearing fan, although they tend to be a little noisier than sleeved/hysint bearing fans, but their lifetime is much longer. A higher-quality fan would be more appropriate given the price tag of the PSU. Speaking of price tags, the MSRP of this unit is surely on the high side, and it will have a really rough time if it lands on the US market with a price close to $160. Finally, its warranty period should ideally be five or more years since the GT-700SG plays ball in the high-end category where the competition offers units with a warranty of up to seven years.

To sum up, the GT-700SG is a great looking unit that performs well in all areas. It is surely not a record breaker, but it will meet the competition eye-to-eye, especially if Aerocool manages to provide the unit at a lower price to pick its price/performance ratio up, which would give it a great viability boost. The GT-700SG would actually gain a "recommended" award from me if it was more affordable.

Fractal Design NEWTON R3 1000 W Review - TPU

Quote:

The Fractal Design Newton R3 1000W retails for $209.99

Delivered full power at 45°C
Decent price/performance ratio
Highly efficient throughout all load range
Good enough ripple suppression at +12V
Tight voltage regulation
Semi-fanless operation
Quiet fan under normal conditions
Stealth modular cables
5 year warranty

Ripple suppression on the minor rails
Low hold-up time
There could be less native cables

The fresh Newton R3 with 1 kW capacity is a very good performer, with the exception of high ripple on the minor rails. It managed to keep tight voltage regulation on all rails despite the tough conditions I used for all tests, and the efficiency levels it achieved were simply amazing. I think this platform has much potential, and the new Newton would gain a much higher placement, near the top of the corresponding performance graph, if ripple on the minors were lower.
The other interesting features of this unit are its semi-fanless mode, modular stealth cables, and five-year warranty. We have come across the semi-fanless mode feature a lot lately, especially in highly efficient units; it allows for completely silent operation at low loads and under normal ambient. The price of this PSU is also right on the spot given its features. Its only direct competitor is Rosewill's Platinum 1 kW unit; however, that unit is only available in the US.

To wrap up, the Newton R3 100W is a fine unit with extra-high efficiency throughout its entire load range and ultra-stable DC outputs. Sure, its already high performance could be even higher with lower ripple on the minor rails, but real-life use probably won't stress the minor rails enough for their increased ripple to be worrisome. You should keep in mind that the most important thing in a modern PSU is the +12V rail, and the +12V rail of the Newton R3 is really good.

Lepa G650 – Test practic - lab501

Quote:

Inainte sa ma apuc de testat, chiar imi doream sa imi placa Lepa G650. Dupa bundle si constructie iti dai seama ca e o sursa modesta, in sensul bun al cuvantului, iar asta se va reflecta probabil in pretul de comercializare. Ca urmare, daca se dovedea a fi o sursa silentioasa si de incredere, din punctul meu de vedere ar fi ajuns sus in lista recomandarilor.
Cel mai mare minus este zgomotul de motor emis de ventilator, pentru ca in cazul exemplarului de fata este deranjant. Nivelul de performanta demonstrat de sursa Lepa nu poate fi considerat slab. Avem de-a face cu o sursa 80Plus Gold care nu a ajuns in niciun moment cu voltajele sub valorile lor nominale si a putut alimenta, in mod stabil, sistemul pana la 650W, puterea inscrisa pe eticheta. Dar prin comparatie cu alte surse din aceeasi categorie, precum Seasonic Gold, electronica nu este la fel de performanta.
Pretul ar trebui sa fie insa de partea sursei Lepa, iar daca diferenta va fi suficient de mare consider ca G650 e o alegere chiar buna. Stabilitatea voltajelor, temperatura de functionare si nivelul de zgomot sunt suficient de bune din punctul meu de vedere, iar un pret suficient de accesibil ar putea sa insemne ca diferenta pana la sursa mai scumpa sa nu merite. Daca zgomotul de motor al ventilatorului nu se dovedeste a fi o problema raspandita, G650 cu siguranta este o sursa mainstream care isi indeplineste rolul asa cum trebuie.
In concluzie, am avut ocazia sa testam o sursa nu extraordinara, nu iesita din comun, insa cinstita, care face exact ce spune ca va face si capabila sa tina in frau un sistem dual-GPU. E greu de crezut ca cineva va imperechea un 3960X, doua HD7970 si o astfel de sursa, asa ca va putea exista si ceva overclock pe acolo. Impresia finala e urmatoarea: daca zgomotul de motor a fost o problema izolata iar pretul va fi potrivit, Lepa G650 este o sursa la care merita sa va uitati. Lucru care ma face curios in legatura cu urmatoarele produse de la acest producator.
