Ripple Measurements

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.

    This one looks like a pass. Much better units out there. Too bad, I wish the best for BeQuiet!
    Another review:
    For not too many $ more you can get a Seasonic G series.
    With quality components-better design-better performance,
    and to top it off a longer warranty................................

    Avoid these low end PSU's......................
