To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the Quark 1000's rails. The limits are, according to the ATX specification, 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Ripple suppression was pretty good on all rails. Only Super Flower's platforms managed to outperform this one's ripple performance at +12V, which is the rail we really care about since it feeds most system components.
Ripple Oscilloscope Screenshots
The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
