Well the issue there is the PSU wont be sucking 650w out of the wall socket.
It comes down to how efficient the PSU is, if its say 80% efficient, it would need to pull 812w from the wall.
then theres the cost per KW/hr your elec company charges you.
More like a total of around 300- 350W for that one GTX580 GPU and the entire system,

Thats pretty expensive when you work it all out - im quite shocked.
