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).

Ripple Measurements Corsair CX600M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	12.2 mV	8.2 mV	9.4 mV	9.9 mV	Pass
40% Load	15.5 mV	8.6 mV	10.4 mV	11.7 mV	Pass
50% Load	17.0 mV	10.1 mV	11.3 mV	13.0 mV	Pass
60% Load	20.0 mV	10.7 mV	12.2 mV	14.2 mV	Pass
80% Load	28.7 mV	11.7 mV	14.3 mV	16.8 mV	Pass
100% Load	41.2 mV	13.9 mV	20.1 mV	23.5 mV	Pass
110% Load	59.1 mV	18.6 mV	26.5 mV	30.4 mV	Pass
Crossload 1	12.9 mV	20.1 mV	10.9 mV	9.7 mV	Pass
Crossload 2	53.1 mV	20.5 mV	22.9 mV	25.9 mV	Pass

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.
