If you want to look at power draws of just the cards themselves isolated from the rest of the system, see charts here (warning: 7950 is highlighted in green here, in case you look too quickly, not 7970):

Hi guys. I need help.

I want to know if my Enermax Revolution 950W will be enough for my rampage IV extreme with 3930k OC to 4.8 Ghz with 3x6970 and 16 GB Ram

I only have one HDD and one SSD and around 20 Fans + two MCP 655 Pumps

Thank you

The Revo85+ 950W can output considerably more than it's rated for while only sustaining minor efficiency drops.. you're fine wink.gif

I've had problems with my HCP-850w with my new SB-E build using the same video cards, just not enough power. Never a problem with my 990x. Your new 3930k @ 4.8GHz will take too much power along with three 6970s to run properly on a 950w Enermax Revolution.

The OCZ ZX-series has REALLY short cables! I don't think OCZ have ever heard of cable management!
If you're getting it, be sure to pick up some extensions for the 8 pin motherboard connector, and the 24-pin wink.gif

He'll be fine with three too.. also, your HCP 850W can deliver more than enough power for your setup, it can actually do ~1100W continuously wink.gif.. however, due to its rail arrangement, you need to fiddle a little with the connectors and get a configuration that will not hit OCP threshold on any rail.

If you're doing moderate OCs on the cards and cpu, then a good 850w is fine. Otherwise go for a good 1000w if you can for some headroom.

My Antec is really stressing now since I change out from a 990x to this 3960x. I'm thinking of buying a HCP-1200 tomorrow.

well based off max-load draws from benches at Anandtech, you're looking at a possible 357-391W draw from each 7970. That would leave you with around 50-150W leftover for the rest of your PC. If I were you, I'd try to find a 1000W, just for peace of mind.
