Ripple Measurements

You will see the ripple levels that we measured on the main rails of the TRIATHLOR FC 550 W in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple Measurements Enermax ETA550AWT-M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	15.2 mV	7.4 mV	5.6 mV	10.5 mV	Pass
40% Load	17.8 mV	7.5 mV	6.6 mV	11.3 mV	Pass
50% Load	20.7 mV	8.9 mV	7.7 mV	12.7 mV	Pass
60% Load	26.4 mV	9.6 mV	8.4 mV	13.3 mV	Pass
80% Load	30.7 mV	10.9 mV	9.1 mV	11.0 mV	Pass
100% Load	36.5 mV	11.2 mV	10.2 mV	13.5 mV	Pass
110% Load	39.9 mV	11.7 mV	10.7 mV	14.4 mV	Pass
Crossload 1	17.2 mV	8.6 mV	12.0 mV	10.7 mV	Pass
Crossload 2	35.4 mV	10.0 mV	7.1 mV	12.2 mV	Pass

Ripple suppression is really good on all rails. It is especially top notch on the minor rails! Such overall ripple performance easily meets even the high-end competition, with the latter costing way more. Enermax surely deserves praise for the performance of the Triathlor FC 550 W in this area—one of the most significant performance segments to a PSU.

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 0.01 V) as standard.
