The efficiency and power factor levels easily meet the ATX12V V2.2 specification, but how do the figures stack up against its claimed 80 Plus Bronze certification? Bronze level certification requires a power factor of 0.9 at 50% DC loading and efficiencies of 82%, 85% and 82% at 20%, 50% and 100% DC loading and as can be seen from the results the levels are as required. Absolutely no problems here, so let's move on and have a look at DC quality.

 

AC Ripple On DC Outputs:

 

I have consistently found the AC ripple levels on the DC rails to be more or less equal with a 110VAC or 230VAC mains supply. The results given below are for 230VAC only but I will continue to check the levels at 110VAC during testing and publish them below if there are any significant differences.

 

AC Ripple On +3V3 Rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 10uS/div

 

AC Ripple On +5V0 Rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 10uS/div

 

AC Ripple On +12V Rail at 230VAC

Oscilloscope settings: Amplitude = 20mv/div, Timebase = 10uS/div

 

AC Ripple On -12V Rail at 230VAC

Oscilloscope settings: Amplitude = 20mv/div, Timebase = 10uS/div

 

AC Ripple On +5VSB Rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 10uS/div

The Thermaltake Toughpower XT 775W noise/ripple levels on all the DC rails are all within the limits set down by the ATX12V V2.2 specification. No problems here, so let's move on.
