Ripple Measurements

In the following table, you will see the ripple levels that we measured on the main rails of the HX850. According to the ATX specification, the limits are 120 mV (+12 V) and 50 mV (5 V, 3.3 V, and 5VSB).

100% Load	28.4 mV	16.1 mV	17.2 mV	23.4 mV	Pass
Crossload 1	13.4 mV	12.6 mV	13.5 mV	9.0 mV	Pass
Crossload 2	26.6 mV	16.9 mV	16.7 mV	23.0 mV	Pass

Ripple suppression is excellent on all rails, something usual for a Corsair unit since this company pays extra attention to ripple filtering on all of its power supply products. Of course, CWT's technicians did their part in this performance.

Ripple at Full Load

In the following oscilloscope screenshots, you can see the AC ripple and noise that the main rails registered (+12 V, 5 V, 3.3 V, and 5 VSB). 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.
