Gtx 670 sli PSI

[z7storm7z]

I have a single gtx 670 ftw and a be quiet! Pure power 630w psu. I am thinking that in some point in the future I will get another 670ftw, can my psu run it? I have a i5-3570k a ssd, 3 fans and 8gb of ram. I am only thinking of OCing my CPU if my psu can support both gpus also.

It can theoretically but does it have 4 PCIe power connectors for the 2 cards. 750watts is what is actually recommended for that SLI setup and quality 750watt PSU's come with 4 connectors.

Yes it does have four connectors

With 4 connectors I would try it. Here you have total system power 433watt with 2 670 in full stress http://www.guru3d.com/articles_pages/geforce_gtx_670_2_and_3way_sli_review,4.html
