EVGA SuperNOVA NEX 650 G 80 PLUS GOLD vs Antec HCG M HCG-750M 750W

Solution
The Antec HCG series of PSU's are quite good, with quality components and quality build. Generally the EVGA NEX series of PSU's are not quite so good due to lower grade componentry. But the 650 W PSU uses, generally, good components, but its performance is not quite as good as the Antec HCG-M 750 W PSU.

The Antec HCG PSU is the better choice here.
