Ripple Measurements

You will see the ripple levels we measured on the main rails of the SF-1300F14MG in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple suppression was out of this world. It has been a while since we last looked at such low ripple values, especially in a unit that can deliver as much power. SF did an excellent job in this section (and not only). The Japanese caps on the main PCB also ensure that the unit keeps its topnotch performance for quite a while.

Ripple at Full Load

In the following oscilloscope screenshots, you can see the AC ripple and noise the main rails registered (+12V, 5V, 3.3V, and 5VSB). The bigger the fluctuations on the oscilloscope's screen, the bigger the ripple/noise. For all measurements, we set 0.01 V/Div as standard (each vertical division/box equals 0.01 V).
