Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HCG-520. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V & 3.3V).

Ripple Measurements
Test	12 V	5 V	3.3 V	Pass/Fail
20% Load	7.0 mV	3.0 mV	5.0 mV	Pass
40% Load	9.2 mV	3.8 mV	5.8 mV	Pass
50% Load	10.4 mV	4.2 mV	6.2 mV	Pass
60% Load	11.4 mV	4.6 mV	6.4 mV	Pass
80% Load	13.6 mV	4.8 mV	8.4 mV	Pass
100% Load	17.0 mV	5.8 mV	11.8 mV	Pass
Crossload 1	13.4 mV	21.6 mV	5.8 mV	Pass
Crossload 2	18.2 mV	4.4 mV	13.2 mV	Pass

Ripple and noise suppression are excellent throughout all loads/tests. Since Seasonic is the OEM of this PSU, this terrific performance, especially for a low budget PSU, didn't come as much of a surprise.

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). 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 to 0.01V) as standard but sometimes we are forced to use 0.02 V/Div, meaning that the fluctuations will look smaller but actually this wont be the case. For the first screenshot we used 0.02 V/Div, so actually the registered ripple is much bigger than it seems (compared to the other screenshots where 0.01 V/Div was used).
