To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the BWG550M's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Ripple suppression is great, especially at 3.3V! CWT offered Bitfenix a great platform, and now the company has a real weapon in its arsenal for infiltrating the competitive PSU market.
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 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
