Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of SP-750M. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements Thermaltake SP-750M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	9.8 mV	16.2 mV	14.2 mV	7.1 mV	Pass
40% Load	14.3 mV	19.3 mV	17.6 mV	8.7 mV	Pass
50% Load	17.4 mV	20.1 mV	17.9 mV	9.6 mV	Pass
60% Load	20.1 mV	21.1 mV	18.7 mV	10.2 mV	Pass
80% Load	26.0 mV	22.8 mV	20.0 mV	13.0 mV	Pass
100% Load	33.1 mV	23.8 mV	20.5 mV	15.5 mV	Pass
Crossload 1	16.8 mV	20.0 mV	17.5 mV	6.9 mV	Pass
Crossload 2	30.7 mV	21.7 mV	19.3 mV	14.3 mV	Pass

Ripple suppression is quite good, especially on the +12V rail which is the most important of all. Apparently this platform is ripple proof and delivers very clean DC outputs so it won't stress sensitive electronic components (e.g. capacitors). After all CWT proved many times in the past that they posses the essential know-how to fight ripple.

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.
