Ripple Measurements

You will see the ripple levels we measured on the main rails of the Leadex-1000 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 Super Flower SF-1000F-14MP
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	9.9 mV	9.9 mV	17.8 mV	4.5 mV	Pass
40% Load	11.3 mV	8.1 mV	8.5 mV	4.5 mV	Pass
50% Load	12.2 mV	7.1 mV	8.4 mV	5.2 mV	Pass
60% Load	12.7 mV	8.8 mV	9.1 mV	6.1 mV	Pass
80% Load	14.0 mV	8.8 mV	10.6 mV	6.8 mV	Pass
100% Load	15.6 mV	9.4 mV	11.7 mV	7.5 mV	Pass
110% Load	16.5 mV	9.8 mV	12.9 mV	7.7 mV	Pass
Crossload 1	14.5 mV	6.1 mV	7.8 mV	21.1 mV	Pass
Crossload 2	15.7 mV	7.3 mV	11.3 mV	5.4 mV	Pass

Ripple suppression is excellent and worthy of a high-end unit costing over 200 bucks. SF units never had a problem with ripple suppression but the new Leadex PSUs raised the bar even higher, showing that digital control isn't essential for ultra clean DC outputs.

Ripple at Full Load

You can see the AC ripple and noise that the main rails registered (+12V, 5V, 3.3V, and 5VSB) in the following oscilloscope screenshots. 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.
