Noise and Ripple


Noise and Ripple can easily be measured by an oscilloscope. These show how much voltage fluctuation there is on a particular rail. We tested the rail stability of the 3.3 volt, 5 volt and 12 volt rails using an identical time and millivolt scale for all graphs.

The latest ATX 12 volt version 2.3 specifications state that ripple from peak to peak must be no higher than 50 millivolts for the 3.3 volt and 5 volt rails, while the 12 volt rail is allowed up to 120 millivolts peak to peak to stay within specifications.

40 Enermax T7 40 3 Volt Enermax T7 40 5 volt Enermax T7 40 12 volt
60 Enermax T7 60 3 volt Enermax T7 60 5 volt Enermax T7 60 12 volt
80 Enermax T7 80 3 volt Enermax T7 80 5 volt Enermax T7 80 12 volt
100 Enermax T7 100 3 volt Enermax T7 100 5 Volt Enermax T7 100 12 volt
