Default power supply size

I need some help picking a power supply for a new build. I have a I7 920 processor, Asus P6T Deluxe motherboard, 6 Gb OCZ ram with a 285 GTX 2 gig Video card. I would like to water cool this since I want to overclock the processor to at least 4.2 gig. I was planning to use a 1000w Corsair power supply. If I watercool the video card will a 1000w power supply be big enough? Any suggestions would be appreciated.

well at a minimum you really only need a good quality 650w PSU.

how much are you willing to spend?

As Philbar said 650w is enough. Im running a very similar system on a 550w fine [although i think its holding back my o/c a bit].

Corsair PSUs are very good, but if I were you I would only get a 1000w psu if you plan on going SLI or tri-SLI in the future.

Philbar the Corsair 1000w is $240 at Newegg and I would like to keep the price in that general range or below.

Just get the Corsair 850w and you'll have plenty of power even if you decide to go SLI in the future

And if you don't mind the extra cost, get the modular 850W (850HX), makes working with the cables much easier.
