Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HCG-620M. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

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.
