Ripple Measurements

You will see the ripple levels we measured on the ERX430AWT's rails in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple suppression on the +12V rail was decent; however, we would much prefer results below 40-45 mV. Performance on the other three rails was good overall, with only the 5V rail exceeding 30 mV, which is still well below the 50 mV limit.

Ripple at Full Load

You can see the AC ripple and noise the main rails registered (+12V, 5V, 3.3V, and 5VSB) in the following oscilloscope screenshots. The bigger the fluctuations on the oscilloscope's screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01 V) as the standard for all measurements.
