Ripple Measurements

You will see the ripple levels we measured on the main rails of the Leadex-1200 in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

20% Load	8.8 mV	6.3 mV	10.0 mV	4.7 mV	Pass
40% Load	10.0 mV	6.8 mV	10.6 mV	5.0 mV	Pass
50% Load	11.9 mV	5.8 mV	11.8 mV	5.7 mV	Pass
60% Load	11.9 mV	6.8 mV	12.3 mV	6.3 mV	Pass
80% Load	14.3 mV	9.0 mV	13.7 mV	7.4 mV	Pass
100% Load	16.4 mV	9.1 mV	15.2 mV	7.9 mV	Pass
110% Load	17.1 mV	9.3 mV	16.9 mV	7.8 mV	Pass
Crossload 1	9.6 mV	5.8 mV	7.8 mV	18.9 mV	Pass
Crossload 2	15.2 mV	9.1 mV	14.0 mV	5.7 mV	Pass

Ripple suppression was nothing less but jaw-dropping. SF again showed what a good design and the right caps are capable of. This unit will always provide your components with incredibly clean power to ensure their longevity and stability.

Ripple at Full Load

In the following oscilloscope screenshots, you can see the AC ripple and noise the main rails registered (+12V, 5V, 3.3V, and 5VSB). 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 0.01 V) as the standard for all measurements.
