Okay so I just bought two Zotac GTX 670s 4GB editions brand new off eBay for what I believe to be a good deal. Got both of them for $522 with shipping and like I said they're brand new too. Anyways I'm diffidently going to need a new PSU to run them. But I'm not too good on deciding what PSUs to buy lol.
I plain on OC both GPUs and my CPU to as high as i can get them. The GPUs will be on stock cooler so that won't be too high of a OC but I plain on putting my CPU on a Corsair H100i. So that has be kept in mind for the PSU power too.

Here is a list of all my current components (Future components)
CPU: AMD FX-6350
Mobo: AsRock 990FX Extreme 4
Ram: 8GB(2 x 4GB) of G.Skill Sniper Series @ 1866 (going to add another 8GB soon and might try to OC the ram higher then 1866)
GPU: PNY GTX 580 (Zotac GTX 670 4GB x2) Will OC both
Hard Drive: 750GB Segate (512GB Adata SSD & 4TB WD Black) will remove the 750GB Segate
Fans: 6 Case Fans and two 120mm CPU fans.
Sound Card: HT Omega Claro II
PSU: 600Watt OCZ 80 Plus
Case: CM Haf 912 (Thinking of getting a Haf X, IDK yet if they are good for water cooling)
Also have a Blue ray drive/burner and a fan control unit.

Sorry for the sloppiness but yea, I just want a good PSU that can handle the 2 670s and the cpu with OC and maybe ram OC. Also money is no issue to me so I'm not wanting cheap.

You just need a PSU with four 6 pin connectors. But you might as well get one with four 8(6+2) pin connectors. There are dozens of models to choose from:

I'd go easy on the OC thou. Your FX-6350 is just going to bottleneck those GPU's anyway. Even an 8350 bottlenecks 7970's in crossfire.

But the 670's in SLI will still work good for u. You're not benchmarking against an i7.

I also forgot to mention. I will be adding a PCIe capture card, probably AverMedia live hd gamer or whatever it's called. The good one lol and a PCIe wireless card maybe.

And I figured my FX would be a bottleneck but I want to wait to buy into intel once ddr4 is out. So I will either get Haswell E or Skylake. I just got the fx and motherboard because my old setup was a amd phenome ii x4 965 be and some shitty emachines motherboard with 6gb of ddr2 at 400mhz lol. I just wanred something better but didn't want to go all out yet. So thats why I got the fx. But a 850 will be more then enough then? And should I get a 80 plus platinum or gold?

I think I will go with the Cooler Master then. Since I do, do wire management and it has some nice cables.

And one more question. I have 3 devices that I requires sata power. My HDD, DVD Drive, and Fan Control Unit. Can all 3 run off one sata cord from my PSU since the cord usually has 3 sata connectors on it, or should I use 3 separate cords from my PSU?

Alright thank you. =) Well that answers all my questions. Thanks everyone for your help.

It most likely won't but I will buy some short extensions so it can reach all 3 devices
