4850x2 on 650w psu?

[Starges]

I am planning t upgrade my gpu to 4850x2 in Xfire wit this psu: http://www.ewiz.com/detail.php?name=PS-GX650W&title=Cooler-Master-GX-Series-RS650-ACAAE3-US-650W-ATX-12V-SLI-Power-Supply

Will it supply enough power to support xfire??

mobo: GIGABYTE GA-MA785GT-UD3H

I'd avoid that PSU if its like its 750W brother.

Try buying one from a real good brand. 650W should be ok, you just need a better one.

What about these ones:

From your site and in the $80-90 range, I would recommend the Antec Earthwatts 650w.
It is a high quality unit and will have no issues with your system.

The issue i have with it is that it only ha 22A on each 12v rail.
According to my research i need a psu with at least 30A on the 12v rail if i am planning to ever use X-fire.

You agree?

 

[outlw6669]

Not at all
If you look at how the +12V rails are allocated, you find that +12V3 is dedicated to the two PCIe power connectors.
As there are only one 8 pin (100W) and one 6 pin (75W) PCIe power connector available, only 15A (175W/12V = 14.5833A) is required from this rail.
The 25A provided is more than enough with a little extra to spare.
Combine there are 45A (540W/12V) avaliable accross the +12V rails.

You can locate a good review of the EW650 Here.
From your sites limited options it is one of the best, certainly in your price range.

I have no idea what you just said, all those numbers just messed up my head.

dude omg its enough. 750W ROFL??? Even HD 5970 only need 650W.

I wasn't suggesting he get the 750. I said if the 650W is built the same as the 750W, its not a good PSU like you told him it was.

I agree with the EA650. 650W, and its a good unit unlike the Coolermaster PSU. Should work just fine.
