To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the G-450's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Ripple suppression is excellent on all rails; Seasonic did a fine job here. Some users may say that Super Flower's implementations are better in this area. However, we are satisfied with the G-450's ripple suppression.
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.
