I have recently build a i7 920 rig with the following:
-i7 920 @3.6ghz
3x500gb caviar black in raid0
3x2gb ddr3 1600mhz g-skill pi black
p6t deluxe v2
his hd4870 512mb( from my old computer)
creative extreme audio
OCZ ModXStream Pro 80 plus 700w

I have just bought a gtx295 for cheap today and will be receiving it in the next couple days and was wondering if 700w is enough to handle my current setup+a 295 or should i upgrade to a 850-950w psu. I would truly appreciate any suggestions. thanks

I'm going to have the same problem when I buy mine too.

I read on another forum that a guy's card (GTX 295) wasn't getting to its full potential. The problem was a 750W PSU. He resolved it by getting a 1000W.

I'm planning to go with an 850W PSU, not sure if that'll be enough. I think 1000W seems like overkill though.

yeah I was told by many that 700w is the min requirement but since I'm not running a dual core processor I would probably need more. I heard that they run at 410w@ 100%load 250ish on idle. 1000w are also very pricey at the moment.

1000w is overkill... but the reason I chose it is to allow for OCing headroom as well as the hard drives.

Would I be better off selling the gtx295 when I get it and get the ati6950 that runs alot cooler and requires 250@ 100% load. thanks.

The 295 needs about 335 watts of room for itself.....my son runs an FTW Overclocked one on an SG-850 and the fan barely goes on.

Using this I got 630 watts:

that's odd, I put in extra fans and the cpu overclock did you? I got 865w
