Re: VX 550w for 4850 Xfire
It will run fine, they draw 350W in crossfire, and you have enough amps on the 12v
Re: VX 550w for 4850 Xfire
Yeah I agree with above, your psu will be perfectly fine for 2*4850s in crossifre. TBH I'm not sure what that review means, that 1000W OCZ Psu (if working properely) would be able to handle 3*4850s in crossfire.
Re: VX 550w for 4850 Xfire
Yeah, I'd have to read that Anandtech article first. A true 1000w PSU should run 3+ of ANY video card made. THe VX550 will run your Crossfire setup easily.
