We were really impressed by this power supply. It not only could deliver its labeled power at 50º C, but we could pull up to 868 W also at 50º C!
Efficiency was one of the highlights of this product during our tests. If you pull up to 80% of its labeled capacity (i.e. up to 600 W) you will have at least 85% efficiency, peaking almost 90% when you pull 40% of its capacity (300 W). We could see an efficiency of 82.8% when it was delivering 750 W, which isn’t bad at all! Even when we overloaded it efficiency was still above 80%.
It is a very quiet power supply if you run it below its maximum capacity.
Featuring a 5-year warranty (the product box says 3 years, but it is wrong), four video card power cables (two of them with 6/8-pin connectors) and a sufficient number of peripheral power connectors, this product is perfect for high-end users looking for a power supply on the 750 W-850 W range. And the best of all, it isn’t expensive for a power supply on this power range (it costs between USD 150 and USD 160 in the US), providing a terrific cost/benefit ratio for this kind of user.
Therefore PC Power & Cooling Silencer 750 Quad deserves no less than our “Golden Award” seal.
