Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the TPG-1200F1FAP's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

This platform's ripple suppression is really good, and that's without using in-cable capacitors.

With 110% load, we notice more ripple on the minor rails, which shows how hard we push the platform during our overload test.

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.

    More RGB? *yawn* And is this usefully better in any way in terms of performance, etc. than the old 1275W XT Gold?
