Ripple Measurements

You will see the ripple levels that we measured on the main rails of the AX860 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 superb, something common to all Seasonic products, so this PSU will feed your precious system components with extra-clean DC outputs that will put minimal amounts of stress on sensitive parts like capacitors while ensuring optimal operation and the stability of your system under all conditions.

Ripple at Full Load

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