Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of TX750M. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements Corsair TX750M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	8.9 mV	10.2 mV	11.4 mV	7.6 mV	Pass
40% Load	14.5 mV	12.2 mV	13.1 mV	8.5 mV	Pass
50% Load	16.0 mV	14.0 mV	15.2 mV	10.7 mV	Pass
60% Load	18.6 mV	14.3 mV	15.8 mV	11.5 mV	Pass
80% Load	26.9 mV	16.2 mV	16.3 mV	12.9 mV	Pass
100% Load	35.3 mV	17.4 mV	17.6 mV	14.6 mV	Pass
Crossload 1	14.2 mV	15.8 mV	14.3 mV	14.1 mV	Pass
Crossload 2	32.2 mV	14.3 mV	14.5 mV	10.9 mV	Pass

Ripple/noise suppression is very good on all rails, regardless the load and the operating temperature. Overall excellent performance here, which can easily compete with the Seasonic-made Corsair TX units.

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 0.01V) as standard.
