Ripple Measurements

You will see the ripple levels that we measured on the main rails of the AX860i 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 AX860i
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	7.8 mV	8.1 mV	6.7 mV	4.5 mV	Pass
40% Load	10.7 mV	8.8 mV	6.3 mV	4.7 mV	Pass
50% Load	13.7 mV	9.1 mV	7.1 mV	6.5 mV	Pass
60% Load	14.1 mV	10.6 mV	8.2 mV	6.9 mV	Pass
80% Load	18.9 mV	12.0 mV	8.7 mV	8.1 mV	Pass
100% Load	22.3 mV	14.3 mV	10.2 mV	11.3 mV	Pass
110% Load	23.5 mV	15.4 mV	10.4 mV	11.7 mV	Pass
Crossload 1	7.3 mV	7.5 mV	7.0 mV	4.4 mV	Pass
Crossload 2	22.3 mV	14.5 mV	9.5 mV	11.0 mV	Pass

Ripple suppression is impeccable on all rails, and the new AX860i will give all of your precious system components extra-clean DC outputs that will allow for the highest possible overclock while minimally stressing capacitors and other sensitive electronic parts. The benefits of digital control are, again, pretty self-evident with ripple suppression.

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. We set 0.01 V/Div (each vertical division/box equals to 0.01 V) as standard for all measurements.
