Thermaltake ToughPower Grand RGB Gold (Sync Edition) 750W Power Supply Review


To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the TPG-750AH3FSGR’s rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

Test 12V 5V 3.3V 5VSB Pass/Fail
10% Load 29.7 mV 6.1 mV 6.6 mV 4.3 mV Pass
20% Load 26.8 mV 7.0 mV 8.5 mV 4.4 mV Pass
30% Load 9.9 mV 7.3 mV 9.3 mV 4.5 mV Pass
40% Load 11.9 mV 8.6 mV 9.9 mV 5.7 mV Pass
50% Load 11.9 mV 10.1 mV 11.0 mV 6.0 mV Pass
60% Load 12.7 mV 13.0 mV 12.9 mV 9.2 mV Pass
70% Load 14.2 mV 12.5 mV 12.9 mV 7.4 mV Pass
80% Load 15.4 mV 14.6 mV 14.7 mV 8.7 mV Pass
90% Load 16.8 mV 15.3 mV 15.8 mV 9.5 mV Pass
100% Load 18.8 mV 16.6 mV 16.7 mV 10.5 mV Pass
110% Load 19.9 mV 17.5 mV 17.4 mV 10.3 mV Pass
Crossload 1 22.7 mV 12.4 mV 14.4 mV 6.1 mV Pass
Crossload 2 18.3 mV 12.3 mV 11.3 mV 8.1 mV Pass


The unit delivers clean rails. We might not see the perfect results that Corsair’s units deliver, but still all rails stay below 20mV ripple with full load at 47°C.

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
