Why you can trust Tom's Hardware
To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the SSR-1000PD Ultra's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).
Seasonic's ripple suppression is superb, even without the use of in-cable caps. The company outdoes itself with this fresh Prime Ultra platform.
Ripple Oscilloscope Screenshots
The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V, and 5VSB). The bigger the fluctuations on-screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.

I notice you didn't give it an award rating...what gives, if you present it with such high praise?Reply
It has an award. It is just not shown, yet :)Reply
Lets all hope it doesn't kill your motherboard and all components like my SeaSonic did while only operating 1 year under light workloads. No matter how much change they make to PSU I would not trust a brand that would allow catastrophic results in using their products AND not accept responsibility for the loss.Reply
