Ripple Measurements

You will see the ripple levels that we measured on the main rails of the V1000 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 Cooler Master V1000

20% Load	23.1 mV	11.8 mV	9.5 mV	17.6 mV	Pass

Crossload 1	22.8 mV	13.2 mV	12.0 mV	22.1 mV	Pass
Crossload 2	33.6 mV	13.9 mV	12.2 mV	27.5 mV	Pass

Ripple suppression is fantastic and complements the overall high performance of the unit. CM made a very wise decision by cooperating with Seasonic for their new high-end series, and the following ripple screenshots clearly prove this, since one of the most crucial aspects in a PSU is the quality of its DC outputs, something that is clearly depicted by the AC ripple it registers.

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.
