EVGA SuperNOVA 1600 T2 PSU Review

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the 1600 T2's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

EVGA's ripple suppression is very good. It's only with 110% load that we notice the 3.3V rail misbehaving, reaching close to 30mV. That's operating the PSU beyond its specifications, though, so we can't really complain.

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.
