Ripple Measurements

You will see the ripple levels that we measured on the main rails of the Venom 850 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 Akasa Venom Power 850W
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	11.5 mV	4.5 mV	4.3 mV	7.7 mV	Pass
40% Load	12.3 mV	4.8 mV	4.6 mV	9.6 mV	Pass
50% Load	13.4 mV	5.1 mV	4.7 mV	11.7 mV	Pass
60% Load	15.9 mV	5.3 mV	5.1 mV	13.5 mV	Pass
80% Load	20.2 mV	6.1 mV	6.4 mV	17.5 mV	Pass
100% Load	26.4 mV	6.8 mV	8.2 mV	22.9 mV	Pass
110% Load	30.5 mV	7.2 mV	9.3 mV	25.4 mV	Pass
Crossload 1	10.2 mV	4.4 mV	4.6 mV	6.3 mV	Pass
Crossload 2	27.6 mV	7.2 mV	7.7 mV	12.2 mV	Pass

Ripple suppression is excellent on all rails; that is, even at the 110% load test we conducted. Andyson did a great job in ripple filtering, and the Venom 850 W delivers very clean DC outputs that will contribute well to the longevity of your system's parts. Ripple is, especially on the minor rails, minimal and doesn't exceed 10 mV. This is, undoubtedly, an impressive performance.

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.
