To learn how we measure ripple, please click here.
The following table includes ripple levels we measured on the TPG-0750F-R's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Thermaltake keeps its promise: ripple suppression is very good on all rails. The TPG-0750F-R performs much better than other PSUs based on the same platform, especially when it comes to ripple filtering on the minor rails. Obviously TT's unit has some modifications/fixes on its voltage regulation modules.
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.
