Ripple Measurements

You will see the ripple levels we measured on the rails of the G2-750 in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Crossload 2	14.8 mV	7.8 mV	14.0 mV	8.8 mV	Pass

SF platforms traditionally feature excellent ripple suppression and this one is no exception to the rule. The G2-750 will feed your system incredibly clean power at all times, so you won't have to worry about the quality of power feeding your system and its components, which can easily affect their performance and lifetime.

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.
