Output & Efficiency at 110VAC
DC Load (W)	AC Load (W)	PF	Efficiency (%)	Pass/Fail
0	9	0.50	N/A	N/A
195	245	0.99	80	Pass
474	576	0.99	82	Pass
1027	1285	1.00	80	Pass

 

Output & Efficiency at 230VAC
DC Load (W)	AC Load (W)	PF	Efficiency (%)	Pass/Fail
0	11	0.24	N/A	N/A
195	241	0.91	81	Pass
475	558	0.96	85	Pass
1019	1241	0.97	82	Pass

 

The Thermaltake Toughpower 1000W meets the requirements of the claimed 80 Plus certification on 110VAC and 230VAC (PF>0.9 & Efficiency>80%). Actual measurements once again show the PF to be best at 110VAC and efficiency at 230VAC. Maximum efficiency of 85% is an excellent result and puts this power supply up with the best.

 

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 they differ in any way.

 

AC Ripple On 3V3 Rail at 230VAC

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

 

AC Ripple On 5V0 Rail at 230VAC

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

 

AC Ripple On 12V1 Rail at 230VAC

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

 

Thermaltake Toughpower 1000W AC Ripple/Noise Measurements
DC Output	+3V3	+5V0	+12V	-12V0	+5VSB
Ripple (mV p-p)	30	40	90	80	50

 

The measured levels are a little higher than I would like but they do meet the requirements of the ATX12V V2.2 standard and will not cause any problems so lets move on.
