Ripple Measurements

You will see the ripple levels we measured on the rails of the V1200 in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

The V1200 performed very well, although its direct competitor, the Super Flower Leadex Platinum 1200 W, registered significantly lower ripple on all its rails. A little over 35 mV ripple on the +12V rail with 1200 W load and at close to 45°C ambient isn't commonplace. Such performance will definitely allow your components to unfold their full potential. We should state that the only area where the V1200 failed to at least match the tough competition was ripple suppression, and while we are well aware that its ripple suppression is very good, similar PSUs by the competition were simply amazing, which forced us to deduct those critical performance points which kept it from placing well in our relative performance chart.

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.
