The over-power protection feature is set too high. To the 650 B3's credit, though, at least it didn't die like EVGA's 450 B3, 750 B3, and 850 B3 during the same test.
Over-current protection on the minor rails is configured reasonably well, while the power-good signal is accurate. We do not approve of EVGA's decision to omit a bypass relay, which would have allowed the NTC thermistor to remain at a low temperature with the PSU running. That way, it could provide protection during a hot restart with the bulk cap being discharged.

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

redgarl 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! -

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.
