Recommended PSU Wattage for 2 Graphic Cards.

For the computer in your sig? Corsair TX-650 or an OCZ GameXStream 700w. Something a bit bigger if you want to go dual GPU's or you have like 50 hard drives and 20 dvd drives :P:cool:

Yessir. That is what I was planning to do., yet i'm still undecided. Possiblely adding another 4870 HD into my rig & going crossfire, or Just buying the Asus HD 4870X2. I first wanna see the options and the benifits / comparisons. I'm hoping to make my final deadline purchases by sometime in mid Febuary.
 
Why not get a 5000 series card? the 5850 or 5870 if you can find them. mostly they are out of stock everywhere, or you could wait for nvidia to release their dx11 cards.

As for a PSU, with dual GPU's you need more amps and watts on the +12v rail so maybe the Corsair TX-850 or a higher wattage OCZ GameXStream (i don't know too much about them) or a good coolermaster, their 750w units are nice.

I still think the OCZ GameXStream 700w could handle a 4870x2 or 2x 4870's but in my opinion it's not worth the extra cost. plus with one better card you lessen your power bill ;)
 
Right, Basically i'm planning to get a PSU that can support CF of 2x Sapphire Vapor-X 5870. I don't plan on going into CF mode right away, but im definitly planning in early 2011 to go into CF mode.

What PSU's should I go with now, a 750w or 850w supply ? to support with i7 / CF is thats important.
 
Should I still go with the one bigfella reccomended the first time. I plan on OC my PSU would that involve more power consumption plus CF & an upgrade cpuhooler/heatsink i'll post what I think is appropriate and you guys tell me what you think i'm gunna get this settled right now
 
The Seasonic is the best, however the 650W Corsair is fine with 52A. You are not going to pull 600A on the 12V rail ever.
