EVGA's 650 B3 power supply is based on an older Super Flower platform that offers good overall performance. Its only real weakness surfaces during our efficiency benchmarks: the 650 B3 offers mere 80 PLUS Bronze and ETA-A- certifications. Naturally, that means it gets hotter than higher-efficiency models and consequently isn't one of the quietest 650W PSUs we've tested. So why does it bear a similar price tag as 80 PLUS Gold-rated competitors like Corsair's TX650M? Good question. Instead of selling for $75, the 650 B3 should really be in the $60 to $65 range. Still, thanks to high overall performance, it achieves a fair value score after completing our suite of benchmarks.
