The following table includes the ripple levels we measured on the SF-550F14MG's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Super Flower has proven many times that it is the master of ripple suppression and this Leadex platform clearly shows this. If you want a PSU with super-clean, AC fluctuation-free rails, then this unit is an ideal choice; it's as simple as that.
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.
