Corsair AX1600i PSU Review

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the AX1600i's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

The AX1600i's ripple suppression is amazing! Besides super-tight load regulation, this digital platform also allows for DC rails that are clear of ripple.

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.
