Max draw for one GTX280 is around 230w, With tri sli scale, it may need 570w from 12v alone. With other components, I would go for a solid 900W+ psu such as Corsair 1000hx.

Assuming you will be OCing, minimum is a 1000W PSU with 80A on the 12V rail. But if you are going to drop well over a grand on parts, you should go ahead and spend the extra to get a 1200W with ~90A. Something like the Thermaltake Toughpower or the Ikonik 1200W when it comes out. The Silverstone ZM1200M is also one of the best around.

Ultra X3 1600watt psu.
Just kidding, maybe if you wanted about 6 GTX280s.

1000watt Corsair. I've seen it cheaper than $210 before though.
