Hi, I have an old system, which I am planning to upgrade. The only things I want to keep are the hard drives, the DVD-RW, my 4850 and the PSU (it's a Corsair 450VX).
I was planning on getting an i5 or a high end Phenom II. My question is, do you think that my PSU with 33A on its single 12V rail can handle two 4850s (since I am planning on getting another one and crossfiring it)? I know the requirements ask for a 550W PSU, but mine is a good one.
Do you think it can handle it? (I am not planning on overclocking, by the way, nor will I put a lot of hard drives in there. 2 is enough).
get the raidmax 530w psu as an absolute minimum to run that setup.
As much as the 12v may have 33A on it there's also the other rails that have to balalnce depending on all other components utilising other rails(most specifically the 5v) because you could easily exceed the max allowable power draw for that PSU for the combined 12v & 5v rails.
