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 temperature results of the XFX Pro Series Core Edition power supplies produced nothing remarkable and are typical of power supplies in this class. Fan noise remained low up to approximately 50% DC loading but noticeably louder when hitting 2000 RPM plus across the board at full load.
