Ripple Measurements

You will see the ripple levels that we measured on the main rails of the Commander III 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 is not so good at +12V, and we expected much better ripple suppression on this rail from the new Commander. Surely 70 mV, as its poorest value, won't pose a threat to your system's components, but we don't expect to see over 50 mV of ripple on this rail, especially with a good, modern PSU. In Win should look into this matter and find a way to further suppress ripple at +12V. On the other hand, ripple suppression on the minor rails is quite good, indicating that the DC-DC converters are equipped with proper components that are correctly tuned.

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 0.01 V) as standard.
