Need suggestion for a good psu

[sreemodh]

I m planning to buy a new psu
which one out of these is better?
(i) Corsair CMPSU-500CXV2UK 500 Watts PSU
(ii) Seasonic S12II 520 Watts PSU
i m supposed to use it with an amd6850.
Can i use either of these for crossfire?

Crossfire will be too much to ask from any one of them.
If you want to run dual graphics cards I'd suggest you opt for 700 or more watts of psu to be on the safer side.

Seasonic S12II-520 is a far better option.
If you are willing to XFire two HD 6850s then get Seasonic S12II-620 for 1k more.

Or you can get Corsair GS-700 for the same price as that of S12II-620.
