600W - 650W for SLI in default can handle it , since you OC GPU get 750W or + OC CPU get 800W or more power .. i think many PSU from antec / corsair / Seasonic /xfx and dependt your budget :D

just read at label if no more power and no Certified SLI-Ready Power Supplies that can't be used , see GTX 670 need Supplementary Power Connectors 2 x 6pin

I'd get 750-800W. But it has to be decent brand and 80 PLUS.
