700W enough for 4850 Crossfire?

Anyone think this PSU could handle 2 4850s, or 2 8800GTXs?

Also, what's the deal with multiple +12v rails? Does that mean if you have a card that requires a lot of amps the PSU won't be able to handle it because it's split all its' amps up over multiple rails?

dont have an idea... all i kno is + = better,

i have a Q too... ive found a PSU with 3 rails, with 19A each, and another with 44A on a single rail... wich is better?

Yeah, that's what I'd like to know.

Would 620W power 2 HD 4850s? I'm looking at the Corsair TX now, because it's modular

Yes for sure. That's a great power supply. You need a mimimum 550W psu for 2 x 4850.

For one yeah no problem, the 4850 isn't too power hungry. Max TDP is 110W.

Great :) Yeah this PSU looks the bee's knees, and it's the same price as the Coolermaster, albiet 100W less powerful. I'm more worried about reliability, so as long as it can handle those in SLi or Crossfire, I'm pretty happy :)

Two HD 4850's in Xfire require AT LEAST a 550w PSU. I would say go with a 620w-650w just to be safe. As far as rails go, as long as you have a quality brand PSU it really does not matter. The only three brands I would ever reccomend to buy from are Rosewill (my personal favorite), Thermaltake, and Corsair.chandlerr_360

Rosewill is one I would recommend against, same as thermaltake, other than their tough power series. Now Corsair is good, but they are made by Seasonic (one of the best easily) and Channel Well
