Ripple Measurements

You will see the ripple levels that we measured on the main rails of the P10-PRO-1000 in the following table. According to the ATX specification, the limits are 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple Measurements Be Quiet P10-PRO-1000
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	20.9 mV	7.8 mV	9.7 mV	13.0 mV	Pass
40% Load	17.2 mV	9.5 mV	9.3 mV	18.9 mV	Pass
50% Load	16.3 mV	10.4 mV	10.4 mV	8.1 mV	Pass
60% Load	17.1 mV	11.6 mV	11.6 mV	9.0 mV	Pass
80% Load	20.9 mV	14.1 mV	12.7 mV	10.4 mV	Pass
100% Load	27.2 mV	17.5 mV	15.5 mV	12.2 mV	Pass
Crossload 1	26.0 mV	14.2 mV	10.8 mV	11.3 mV	Pass
Crossload 2	27.2 mV	12.5 mV	17.6 mV	21.2 mV	Pass

This PSU couldn't have done otherwise but to register extra-low ripple on all rails since it is made by Seasonic and uses the best available components. The max ripple we measured at +12V rail was 27.2 mV, while none of the minor rails even reached close to 20 mV. Such great results didn't take us by surprise and this platform, like all Seasonic ones, is ripple proof.

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 to 0.01 V) as standard.
