Ripple Measurements

In the following table, you will see the ripple levels that we measured on the main rails of the TPX-1375M. According to the ATX specification, the limits are 120 mV (+12 V) and 50 mV (5 V, 3.3 V, and 5VSB).

Ripple Measurements Thermaltake TPX-1375M
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	14.0 mV	11.7 mV	17.6 mV	17.0 mV	Pass
40% Load	24.3 mV	14.5 mV	21.6 mV	19.4 mV	Pass
50% Load	23.6 mV	16.1 mV	24.8 mV	24.2 mV	Pass
60% Load	25.3 mV	19.3 mV	25.3 mV	23.4 mV	Pass
80% Load	32.0 mV	21.7 mV	30.3 mV	26.3 mV	Pass
100% Load	41.6 mV	23.1 mV	36.4 mV	28.7 mV	Pass
Crossload 1	17.6 mV	14.9 mV	29.2 mV	18.6 mV	Pass
Crossload 2	38.2 mV	20.5 mV	23.9 mV	27.3 mV	Pass

On the +12 V and 5 V rails, ripple suppression is excellent, while on the 5VSB it is decent, and, finally, at 3.3 V it could be better. Thankfully, a modern system won't stress the 3.3 V rail as much as we did, but, on the other hand, on such an expensive unit we expect all rails to perform well, regardless of their significance.

Ripple at Full Load

In the following oscilloscope screenshots, you can see the AC ripple and noise that the main rails registered (+12 V, 5 V, 3.3 V, 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.
