GTX 580 SLI - too much for my PSU?

[tummelv]

I have a Corsair TX Series 650W PSU. Is this enough for GTX 580 in SLI? I'm pretty sure I already know the answer to this and it's a no but I thought I'd double check just to be sure.

Thanks,

I know I wouldn't run that. You'd probably want an 850w for those cards; you don't necessarily want to be running your PSU flat-out anyway.
