|Cougar GX-S 500W - jonnyguru
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.
- very good voltage stability
- very good to excellent ripple suppression
- no problems meeting Gold efficiency
- shallow housing depth
- love that fan
- the unit was a little loosey goosey with the overshoot transient tests - all three of them
- MSRP may mean not so great a value
- I'm out of energy drink... meteoric caffeine crash in 3... 2... 1...

Rosewill Tachyon 1000W - jonnyguru
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.
- very stable voltages
- gave us Platinum efficiency both hot and cold
- outstanding ripple suppression
- semi fanless mode works well
- too many hardwired cables yet
- fan made me worry about long term health
- I have to spend how much on a good DSLR lens?

PC Power&Cooling Silencer Mk III 850W – Test practic - lab501
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.
- shallow housing
- very good voltage stability
- very good ripple control at 12V and 5V
- fully modular
- excellent documentation
- 3.3V ripple could use a little improvement

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
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 Power & Cooling Silencer MK III 750 W Review - TPU
- The PC Power & Cooling Silencer MK III 750 W has an MSRP of $149.99 for the US market and €115.90 for the EU market.
- Resilient to high operating temperatures
- Very good ripple suppression
- Tight enough voltage regulation at +12V
- Highly Efficient
- Selectable semi-fanless operation
- Japanese caps used everywhere
- 7 year warranty
- Flat modular cables
- White case
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.
- No MOV in the transient filtering stage
- Voltage regulation on the minor rails could be tighter
- Hold-up time is lower than the 16ms limit
- Not so efficient 5VSB rail
- Please put a sticker below the fan-mode switch to explain its function.
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
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 Ł124.99 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).
- solid technical design.
- XLR modular connectors are a move forward.
- high efficiency.
- good ripple suppression.
- 7 year warranty.
- facing a lot of competition from the market leaders.

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