I'm considering a 1000W power supply since I now have 2 R9 290s in Xfire on my current PCP&C Quad Red 750 (60A). I saw the EVGA SuperNova 1000 G2 for a decent price ($159 AR) at Newegg, and the ratings are good but there are several complaints of failures. At least it has a 10 year warranty. Any thoughts on this unit? Or is it worth $200 for the Corsair?
