To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the L10-CM-600's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Ripple suppression is quite good at +12V and on the 5VSB rail, and it's good enough at 5V and 5VSB. The performance difference between this PSU and the Pure Power 9 600W is huge in our cross-load tests thanks to the minor rails' independent regulation.
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.
