Ripple Measurements

You will see the ripple levels we measured on the rails of the Corsair AX1600i in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple suppression is jaw-dropping! The digital control and number of filtering caps, and extra caps on some of the cables, are the reasons for such a magnificent result!

Ripple at Full Load

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