Are you going SLI? The 280 is a 250W card. Your system draw total will be around 400W with a single 780. Nvidia suggests a 600W PSU to make up for all the cheap/junk PSUs out there that lie about their power output. A good quality 500-600W PSU is more then enough to run that system, and be at <80% of rated output. My Rosewill 450W can power that. (it has dual 6+2pin PCIe plugs.)
