Need help picking the right psu!

[DaddyDizzle]

Which is the better psu? They're both around the same price. The Hyper Type-R 580 Modular psu looks super sweet but I have no idea how stable it is. The Fortron FX600-GLN has some amazing specs going for it but I can't seem to find any reviews on it. They're both SLI certified and I'm hoping that I'll be able to use either one of these psu's for a few years to come. I have an Opteron 144 cpu, an Asus a8n32-deluxe mobo, a gig of Corsair ram, 2 7800GT's, 2 hd's, and about 4 case fans.
