Ripple Measurements

You will see the ripple levels that we measured on the main rails of the ST60F-PS in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

20% Load	23.4 mV	10.7 mV	14.5 mV	5.4 mV	Pass

Overall ripple suppression is good, especially for this PSU's category. A strange thing we noticed was that the highest ripple reading at +12V was registered with a 40% load. Something is apparently causing increased noise at this load range, but ripple still doesn't exceed 50 mV. The PWM operation of the main switchers most likely caused the dramatic increase of ripple at +12V during the CL1 test, but this is, thankfully, highly unlikely to happen under normal circumstances, so you don't have to worry about it; the ripple was also way below the limit.

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 0.01 V) as standard.
