The GTX 480 does consume a lot of power, possibly an 800W PSU might be needed if you have an o/c i7 for example.

I suspect a GTX480 + GTX260 uses as much energy as 3x GTX260s. 1 GTX480 and a system uses ~506 watts at load. http://www.techspot.com/review/263-nvidia-geforce-gtx-4... A GTX260 adds about another 150watt at load. So I would say go for a quality 800watt PSU and a 850+watt PSU if you want to overclock.
