Ripple Measurements

You will see the ripple levels we measured on the rails of the KL-C1200PL 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 at +12V is lousy. Sirfa apparently decided to sacrifice performance in this area in order to increase efficiency. We would like to see less than 50 mV ripple in our worst-case scenario. The other rails perform better, although definitely not top-notch.

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.
