Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of G700-MA. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements LEPA G700-MA
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	50.5 mV	11.4 mV	9.0 mV	7.9 mV	Pass
40% Load	44.5 mV	14.5 mV	11.4 mV	9.9 mV	Pass
50% Load	46.2 mV	16.8 mV	13.7 mV	11.3 mV	Pass
60% Load	47.1 mV	19.7 mV	16.6 mV	11.9 mV	Pass
80% Load	47.6 mV	21.1 mV	20.2 mV	13.6 mV	Pass
100% Load	48.5 mV	22.6 mV	26.5 mV	14.3 mV	Pass
Crossload 1	54.3 mV	10.4 mV	17.0 mV	10.3 mV	Pass
Crossload 2	48.1 mV	22.8 mV	23.6 mV	14.8 mV	Pass

Ripple suppression in general is decent. At +12V we would like to see lower ripple levels since this unit is based on a high-end platform (until the release of the MaxRevo and Platimax units the Modu87+ was the top line of Enermax). On the minor rails ripple is good although we have seen much better results. One thing is certain though, that the ripple of this unit will not trouble the future buyer; surely it isn't super low but you can't call it bad either.

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 0.01V) as standard.
