Ripple Measurements

You will see the ripple levels that we measured on the main rails of the AX760 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 AX760
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	15.1 mV	11.9 mV	8.8 mV	6.0 mV	Pass
40% Load	17.8 mV	12.4 mV	9.2 mV	6.4 mV	Pass
50% Load	17.6 mV	11.5 mV	9.4 mV	6.6 mV	Pass
60% Load	19.1 mV	12.9 mV	9.9 mV	7.0 mV	Pass
80% Load	21.7 mV	13.5 mV	11.8 mV	7.8 mV	Pass
100% Load	25.6 mV	14.4 mV	12.3 mV	8.5 mV	Pass
110% Load	27.9 mV	14.9 mV	12.4 mV	9.4 mV	Pass
Crossload 1	16.3 mV	14.3 mV	12.2 mV	8.7 mV	Pass
Crossload 2	25.6 mV	13.0 mV	10.5 mV	10.3 mV	Pass

Ripple suppression is simply amazing on all rails. This PSU proudly carries on Seasonic's tradition of being ripple-proof. Even with 110% load, ripple at +12V does not exceed one fourth of the limit. Nearly the same applies to the minor rails. Imagine the potential of this platform with digital control!

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 to 0.01 V) as standard.
