Testing (Continued):
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 Ultra X4 600W power supply cooling fan remained very quiet at low and medium loads with an increase in noise levels at full load which is to be expected. Temperatures remained low and compare favorably with other power supplies in this class.
