pc power and coolingPC Power and Cooling Silencer III 1200W

There is no doubt that the PC Power and Cooling Silencer III 1200W has been built to the highest standards. This top of the range Platinum certified power supply has excellent load regulation and can handle the most demanding of gaming system configurations without suffering from any technical shortcomings.

The high quality white paint work will appeal to the enthusiast user who is looking for something a little different. It will also suit an audience who have purchased a white chassis and want to highlight the insides with LED lighting and a windowed panel.

The quality of modular cabling is also excellent, although we feel there should be 8 PCI e connectors with a 1200W flagship power supply such as this. The latest Corsair and Seasonic units have eight connectors, specifically designed to target the QUAD SLi and Crossfire audience. You will need to use power adapters if you want to run four high end graphics cards with the PC Power and Cooling Silencer III 1200W.

We like the fan inside this unit, it is exceptionally quiet, even when delivering up to 1000W load. The fan does quickly ramp up around 1,100W, but it wouldn’t be realistic for many people to be loading the system at this level on a regular basis. As our review this month highlighted, even with an overclocked, liquid cooled Core i7 3960X and two Sapphire HD7990’s in Quad Crossfire, the system ‘only’ demanded 825W at load.

It is remarkable to think that the PC Power and Cooling Silencer III could deliver this wattage without barely making a noise.

In the United Kingdom you can expect to pay around £225 for this power supply, we found it at Amazon for £221.00 including vat. It is expensive, but it is a superb unit and one that comes very highly recommended.


  • excellent build quality.
  • lovely appearance.
  • cable quality is high.
  • solid technically.
  • almost silent.
  • delivered almost 1,300 watts.


  • only 6 PCI E connectors.
  • faces stiff competition in the £200-£250 sector in 2013.

Kitguru says: We love this power supply, it is basically silent and is a superb all round design.
