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.

    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.

    EVGA, never again, overated like Corsair!

    The B3 have known issues. The G2 and G3 are solid though.

    G3 has similar issues to the B3 based off of Tom's reviews. I'd personally stay away from them.
