Ripple Measurements

You will see the ripple levels that we measured on the main rails of the AX760i 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, although it is not at the levels of the AX1200i, is still outstanding and easily meets the competition, especially on the minor rails. Digital control apparently did its magic again and allowed the PSU to deliver ultra-clean DC outputs that will help a system's components perform at their best even under extreme conditions (severe overclock).

Ripple at Full Load

In the following oscilloscope screenshots, you can see the AC ripple and noise that 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 (each vertical division/box equals to 0.01 V) as standard.
