Ripple Measurements

You will see the ripple levels we measured on the RM1000i's rails in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

10% Load	5.2 mV	7.1 mV	7.5 mV	5.5 mV	Pass
20% Load	6.9 mV	7.3 mV	8.6 mV	6.1 mV	Pass
30% Load	7.5 mV	7.8 mV	8.5 mV	6.6 mV	Pass

100% Load	17.5 mV	13.7 mV	15.5 mV	12.1 mV	Pass
110% Load	23.8 mV	14.0 mV	16.8 mV	13.6 mV	Pass
Crossload 1	7.0 mV	7.5 mV	7.2 mV	7.4 mV	Pass
Crossload 2	17.6 mV	13.8 mV	16.5 mV	11.6 mV	Pass

Ripple suppression was outstanding! Corsair and CWT did a great job here, which raises the bar in this category by a bunch. Taking into account the unit's performance in all the tests we conducted thus far, even the higher-classed Corsair HX1000i will have a hard time competing with it.

Ripple at Full Load

You can see the AC ripple and noise the main rails registered (+12V, 5V, 3.3V, and 5VSB) in the following oscilloscope screenshots. 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 0.01 V) as the standard for all measurements.
