Yes its a very good supply. That case can take up to a 250mm long PSU, the SuperNova 750 G2 is 180mm long, so you'll have no problem fitting it in there.
I think the ninja meant not NEX or G1. I own a G2 series (EVGA SuperNova 1000W G2) and I love it. And there is a 10 year warranty, so you can use it on your next two builds if you get enough wattage.
