You'd be fine just using a Molex-PCIe power adapter and using that PSU. 7850s are only 130w TDP, so 260 from two of 'em, 130w or so stock leaving some spare OCing room still.
If you do want a new PSU (like if you plan to do some solid OCing on both cards and your GPU) look for something in the 550-750w range on this list: http://www.overclockers.com/forums/showthread.php?t=589708
Also check out the reviews on Overclockers.com, funkykit.com and jonnyguru.com.
What's your budget?

Don't really have a budget, I found one for $200 that had a lot of good reviews on newegg a while back but haven't decided what one I want. Unless that adapter you are talking about would work.
You mean something like this? http://www.newegg.com/Product/Product.aspx?Item=N82E16812706017

The card will probably come with an adapter like that, really.
if you have $200 to spend, the brand new Seasonic XP660w is flat out amazing: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=326

Only thing the card came with was a crossfire adapter. I already have 1 7850

Yea I might go ahead and grab that to be on the safe side, because I already OCed my CPU up to 4.0Ghz and my current 7850 is sitting maxed all the way out using ASUS GPUTweak.
Appreciate the help

$150 for a 650W? 
Hell, you can get solid bronze units for half of that...

Yup, but not with very low ripple, 0.23% regulation and 80+ platinum.
Functional difference? Minimal, really.
Theoretical difference? Hard to say.
OMGOMGOMG THIS IS LEIK Z()MG difference? Huge.
It could be argued that a single big GPU would beat a bigger PSU and a second 7850 in performance of course.
