TX 650W Corsair

[Fearthis909]

I'm looking to crossfire two 1gb 6950's with the power supply noted above.

My system specs are as follows:

Amd 955 Black edition from 3.2 overclocked to 3.61ghz

8gb XMS3 1600MHZ corsair ram

Seagate Barricuda 500g 7200 RPM

And of course the 2 6950's (Will not being overclocking)

I was curious on peoples opinions if I could power all of this with my power supply.

Thank for reading my post .

With that psu you should be fine. It's a great unit.

Take a look at this. http://www.tweaktown.com/articles/3942/amd_radeon_hd_6950_1gb_video_card_in_crossfire/index16.html

just saw you made two posts about this in different sections. Same thing said there too.. your good to go.

As long as you're not overclocking, you should be fine.

I built a gaming rig for someone with CF HD6870 1GB cards, and a Q9550 @ 3.5, I used a 750W TruePower New from Antec. Probably overkill, but I needed a PSU with four PCI-E power connectors, and that one was on sale.

But a decent 650W would have worked too, in a pinch.

I've powered two GTX460 1GB cards, overclocked to 840Mhz, and a Q6600 @ 3.6Ghz, all on an Antec EarthWatts 650W (with a pair of PCI-E power cable splitters), for an entire month straight running F@H on both the CPU and GPUs. Not a hiccup.

As it is 80 percent energy efficient does that mean it's only pushing out 520 of the 650w?

Make sure you are only looking at the V2's of those. I think that one is actually the first version. All the v2 enthusiast series are 80 plus bronze which is nice.

What I pretty much look for is, any PSU that is over $60, it has to be 80 plus bronze certified or I wont buy it. Most quality PSU's in the $60+ range should at the very least be 80 plus bronze. Then after about the $90+ range, they should be silver.

It means that to push 650W, it needs to pull ~790W from the wall.

There isn't much reason to prefer the V1 or V2 for any reason other than price. In terms of efficiency they're pretty much equal (<1%) according to plugloadsolutions testing. Bronze certification is what used to be the "80 Plus" criteria.
