How much wattage is good for this 2X 7970 build?

[dsub1994]

Hey guys... just wondering about something that's been driving me mad for some time...
I'm thinking of building a gaming PC soon... here are the specs, just want to know what would be a suitable power supply, since all the PSU calculators give me diffent PSU recommendations...

CPU: AMD FX 8350
dual 7970s crossfire
crosshair V formula motherboard
samsung 830 128 GB SSD
2X2 T.B Seagate Barracuda @7200 RPM
Blu-ray reader/DVD writer
4X4 GB 1866MHZ ram
Antec water cooling kit
I'm thinking of an OK overclock, just reasonable stuff: CPU @4700MHZ and GPU just up a notch.
So guys, what PSU is good?
Thanx

I might be overstating the power supply wattage but I'm going to go with something between 800-1000 watts to be on the safe side. Never hurts to have extra wattage. That being said the specific power supplies I had in mind are the Corsair HX-850 and the HX-1050.

Normally, I recommend a good 750w PSU for SLI/Crossfire setups but that card will pull some power. I would go with a good 1k PSU to be safe.

Although the "needed" wattage is probably somewhere between a good 750 and 1k.

overclocked fx 8350 takes up a ton of power

+1 to this.
If you look closely at the specs, this is actually a 1000w unit.

get 1000watts. Cheaps are from OCZ. But I would recommend corsair if u had the cash. I would also recommend you to get 2 670 as they consume much less power.

Well I wont lie to you but the PCP&C power supply listed is at a fantastic price right now. It's also a top notch brand, take a look at this tier list of power supplies and it falls within tier 2 just like the power supplies I listed. So I would go with Bigcyco's power supply as well.
