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 650 B3’s rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).
The ripple suppression on every rail was excellent, as is usually the case in Super Flower's platforms.
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 the 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.

Definitely priced too high, when you can get a G3 650 for a similar cost.Reply

Phhh, EVGA doesn't equal quality. My Supernova B3 blew up with my EVGA 1080 FTW because my 1080 FTW was defective and my other power supply prevented this whole fiasco.Reply
EVGA, never again, overated like Corsair!
The B3 have known issues. The G2 and G3 are solid though.Reply
G3 has similar issues to the B3 based off of Tom's reviews. I'd personally stay away from them.21146687 said:The B3 have known issues. The G2 and G3 are solid though.
