The Thermaltake Toughpower QFan 650W does not carry 80 Plus certification but it is evident from the above results that it meets the specification and would probably gain certification if submitted. The only claim made in the literature is an efficiency of up to 85% which it didn't quite attain during my tests.

Power factor is excellent at over 0.9 for all loading levels on 110VAC and 230VAC input.

These are excellent results for a power supply in this class.

 

AC Ripple On DC Outputs:

 

The AC ripple/noise levels, with either 110VAC or 230VAC input, were found to be virtually identical when measured on the oscilloscope. I have therefore included oscilloscope screenshots for 230VAC mains input only.

The ripple/noise level on the 12V rails is higher than most power supplies I have tested recently but still remains well within the 120mV level imposed by the ATX12V specification. No problems here so let's move on.
