Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HALE90 850W. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements NZXT HALE90 850W
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	13.7 mV	8.0 mV	10.3 mV	3.8 mV	Pass
40% Load	20.3 mV	9.7 mV	17.5 mV	4.9 mV	Pass
50% Load	22.8 mV	10.5 mV	16.9 mV	5.7 mV	Pass
60% Load	25.0 mV	11.9 mV	17.8 mV	6.2 mV	Pass
80% Load	30.8 mV	14.8 mV	23.9 mV	7.2 mV	Pass
100% Load	35.0 mV	17.3 mV	27.2 mV	8.2 mV	Pass
Crossload 1	24.4 mV	13.0 mV	18.7 mV	4.4 mV	Pass
Crossload 2	29.2 mV	12.2 mV	21.0 mV	7.8 mV	Pass

Ripple suppression at +12V, 5V and 5VSB is excellent. At 3.3V it's a little higher but even in the worst case (100% load test) it stays well below 30mV. This kind or performance here along with the results of all tests we conducted so far, prove that this unit plays in the high-end category not only price-wise but mostly performance-wise.

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.
