Ripple Measurements

You will see the ripple levels that we measured on the main rails of the CX600M in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Overall Ripple suppression is very good despite the highly stressful conditions in which we conducted all of our tests. The Corsair CX600M proved that it can easily operate at temperatures that exceed 40°C while delivering very clean outputs throughout the entire load range.

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.
