The levels required for 80 Plus Gold certification are 87%, 90% and 87% efficiency at 20%, 50% and 100% loading but as usual the measured levels are a little lower following the OCC power supply testing methodology apart from the dip to 83% at 100% loading which is a little unusual. Power factor levels at all times hit the mark, so apart from the dip in efficiency at 100%, no major problems.

Slightly higher efficiency, lower but satisfactory power factors levels and a much improved full load efficiency at 230VAC.

 

AC Ripple On DC Outputs:

 

I have consistently found the AC ripple levels on the DC rails to be more or less equal with an 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/noise on the +3V3 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5uS/div

 

AC ripple/noise on the +5V0 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5uS/div

 

AC ripple/noise on the +12V rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5uS/div

 

AC ripple/noise on the -12V rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 5uS/div

 

AC ripple/noise on the +5VSB rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5uS/div

The Thermaltake Toughpower Grand 1200W power supply produced what can only be described as an adequate set of results in this section. The AC ripple/noise levels on all the rails remained within the limits set down by the ATX12V V2.2 specification, but they are a little on the high side when compared with similar power supplies in this class.
