Ripple Measurements

You will see the ripple levels we measured on the main rails of the HCG-850 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 Antec HCG-850M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	8.9 mV	6.6 mV	9.0 mV	9.0 mV	Pass
40% Load	12.3 mV	7.4 mV	9.9 mV	11.4 mV	Pass
50% Load	13.8 mV	7.6 mV	10.0 mV	11.4 mV	Pass
60% Load	16.1 mV	8.6 mV	10.2 mV	11.4 mV	Pass
80% Load	20.6 mV	8.6 mV	10.4 mV	11.6 mV	Pass
100% Load	26.6 mV	9.5 mV	10.5 mV	13.2 mV	Pass
110% Load	30.3 mV	10.1 mV	12.8 mV	14.8 mV	Pass
Crossload 1	10.6 mV	8.0 mV	8.4 mV	10.1 mV	Pass
Crossload 2	26.8 mV	10.4 mV	10.0 mV	13.4 mV	Pass

Ripple suppression is excellent and worthy of a high-end unit, although this is a mid-range one. The combination of Japanese/Korean caps along with a good design brought about this superb result. When we overpowered the unit, ripple only increased slightly, proving that this platform can easily provide much more juice than its official maximum-rated power output under even tough conditions.

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.
