Ripple Measurements

You will see the ripple levels we measured on the FTX-800-2's rails in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Overall ripple suppression is good. While it is no match to Super Flower's implementations, this PSU will produce clean outputs under even extremely hard conditions.

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.
