PC Power & Cooling Silencer 750 Quad CF-Edition tested

AnandTech took a look at the PC Power & Cooling Silencer 750 Quad CF-Edition power supply. This PSU has a bright red color and features a max output of 750W.

Overall they really like this PSU. Testing shows it has a very high efficiency of 86% and that the build quality is excellent.
From the performance side the results were also excellent. The 3.3V and 12V rails are stable under any temperature and only the 5V rail has any minor flaws. Even these flaws aren't show stoppers, as the results are all well within the specifications. The 750 Quad is able to deliver its specified output, though with the voltage dropping we had slightly less than 750W. Since all voltages remain within spec and the PSU isn't bursting at the seams, there's clearly room for more.

In the area of naming, the Silencer falls a bit short when we look at the real measured noise levels. It is not a noisy power supply as long as the load remains under about 80% and ambient temperatures are below 30°C. The same holds true for most other power supplies, but then most of those don't put "Silence" in their name. To compare this unit with units that use 12cm fans we definitely see some shortcomings, as in our subjective opinion as well as in test results most power supplies with 12cm fans generate much less noise than the Silencer.
