2 x hd 4850 or 2x hd4879 for this psu?

[Johnny Joaozinhe]

Hi all

I'm planning to build a new system and was wondering if I could do 2x4850 (512mb or 1gb) or 2x4870 (also 512mb or 1gb) crossfire on this PSU:

This PSU has only 2xPCI-e connectors and there's something I'm confused about: the hd 4850 512mb has only 1 connector right? Do these two - hd 4850 1gb and hd 4870 512mb - have 1 or 2 connectors? The 4870 1gb has 2 connectors so I can't run 2 of them on this PSU right?

This has been confusing me forever and I can't seem to find a clear answer searching on google and such. Any help would be much appreciated!

Parts list so far:

PS: DO you think I could get cheaper ddr3 ram or should I go with at least the one I listed?


Thank you!

u can use 2x4850 for sure...
and u still can use 2x4870, with 4pin to 6pin molex cables... but that's not recommended...
