The following table includes the ripple levels we measured on the ST1100-TI’s rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).

Test	12V	5V	3.3V	5VSB	Pass/Fail
10% Load	17.3 mV	7.1 mV	6.7 mV	4.2 mV	Pass
20% Load	17.5 mV	10.0 mV	7.8 mV	6.0 mV	Pass
30% Load	19.9 mV	10.5 mV	8.7 mV	5.9 mV	Pass
40% Load	21.3 mV	10.9 mV	9.9 mV	6.3 mV	Pass
50% Load	23.5 mV	11.0 mV	10.9 mV	6.1 mV	Pass
60% Load	21.8 mV	10.6 mV	11.2 mV	5.9 mV	Pass
70% Load	23.9 mV	11.2 mV	12.1 mV	5.9 mV	Pass
80% Load	25.0 mV	12.1 mV	15.7 mV	6.2 mV	Pass
90% Load	25.6 mV	12.7 mV	17.7 mV	6.6 mV	Pass
100% Load	25.4 mV	13.6 mV	15.9 mV	7.1 mV	Pass
110% Load	548.8 mV	20.1 mV	21.6 mV	16.8 mV	Fail
Crossload 1	20.6 mV	11.2 mV	10.3 mV	4.9 mV	Pass
Crossload 2	24.1 mV	11.9 mV	13.3 mV	6.4 mV	Pass

The ripple suppression is very good. Only when we pushed the PSU beyond its limits did we see the +12V rail go south, and besides a huge voltage drop, it also failed to keep ripple in control.

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.
