Deepcool Gamer Storm DQ850-M PSU Review


To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the DQ850-M’s rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

Test 12V 5V 3.3V 5VSB Pass/Fail
10% Load 9.6 mV 12.4 mV 11.4 mV 7.4 mV Pass
20% Load 12.6 mV 13.3 mV 13.0 mV 8.4 mV Pass
30% Load 11.7 mV 13.8 mV 13.0 mV 9.5 mV Pass
40% Load 13.0 mV 13.6 mV 13.8 mV 10.3 mV Pass
50% Load 13.0 mV 14.6 mV 15.0 mV 11.5 mV Pass
60% Load 11.9 mV 15.1 mV 15.7 mV 13.2 mV Pass
70% Load 11.4 mV 17.3 mV 17.5 mV 19.1 mV Pass
80% Load 12.4 mV 17.6 mV 19.6 mV 21.4 mV Pass
90% Load 12.4 mV 17.4 mV 20.8 mV 18.4 mV Pass
100% Load 19.9 mV 18.2 mV 21.9 mV 22.5 mV Pass
110% Load 19.3 mV 18.7 mV 22.5 mV 25.0 mV Pass
Crossload 1 17.4 mV 14.6 mV 21.3 mV 6.5 mV Pass
Crossload 2 18.3 mV 17.5 mV 16.3 mV 17.0 mV Pass

 

The ripple suppression is good overall, despite the lack of extra filtering caps on the modular cables.

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
