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 Thermaltake Litepower 450W remained cool and quiet at all times, even when fully loaded with the fan running at 1600 rpm. The excellent efficiency of the power supply, combined with a large 120mm cooling fan and a maximum power output of only 450W, means little wasted energy on heat - which goes a long way to explaining its ability to remain cool and quiet at all times.
