Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of the VP350P. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

When we have a Delta PSU for testing, there is one section for which we know from the beginning what to expect. This section is of course ripple/noise suppression and the VP350P did very well here, although ripple at +12V is a little higher than what Delta units usually register. Nevertheless we can't call 55mV a high ripple reading, especially in a such a budget PSU and on top of that ripple on the minor rails and 5VSB is very low. Finally we should not forget the fact that the above ripple readings were taken with high operating temperatures, something that most of the times has negative impact on ripple suppression.

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.
