Ripple Measurements

You will see the ripple levels we measured on the main rails of the G2-1300 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	14.4 mV	6.5 mV	9.9 mV	5.8 mV	Pass

Ripple suppression was absolutely fantastic and can easily be an example for the high-end competition to follow. Regardless of the huge power the unit delivered during the full load and overload tests, and the very high ambient inside the hotbox, all DC outputs were super clean, with minimal AC ripple. Super Flower mastered ripple suppression, and they really don't need digital control to achieve awesome results in this section.

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. For all measurements, we set 0.01 V/Div (each vertical division/box equals 0.01 V) as standard.
