So right; I've been upgrading my PC by bits and pieces the last few weeks; and now I'm thinking of getting a twin for my gfx card.

My current one is the ENGTS250 1GB.

Problem is my power supply can barely run it as is and for twins I need a new one.

Problem is; for this one, google doesn't help as I get numbers from 650W to 1000W to run them as twins.

At the moment I'm leaning towards http://www.oczone.co.nz/product_info.php?cPath=38&products_id=34942

So; does anyone know some hard numbers for what power supply I need for twins?

EDIT: King of typos.

 

Though I'm rather computer illiterate (read: dumb), I'm working on a 850W with twin 8800 GTX GPUs. I've never had any problems with power supply, and I doubt you would either, even with the later model. The only issue for me has been cooling....
