Testing:
Temperature, Noise Levels and Fan Speeds:
I am not going to give a pass or fail in this section, as the ATX12V V2.2 does not really have any references on which to base a decision.
Temperatures are purely for information only, as there are too many variables involved when installed in a case, which, by the way, it wasn't. Ambient temperature, processor cooling efficiency and case cooling fans all play their part on the temperature of the air entering the power supply, and consequently the temperature of the air leaving it. No valid conclusions can be made from this test.

The XFX XXX Edition 650W power supply cooling fan was whisper quiet up to 50% loading, but it became noticeably louder at maximum loading. This is to be expected and is on par with other power supplies in this class.
