minimum recommended psu for a 690/7990?

[windheaven]

sorry if this thread has been done before didn't see it,

i'm asking this question because im considering buying one of the dual gpu's i wanted to go for 2 seperate cards..but drivers are scaring me.. plus i'd have to swap my mobo out.

if i were to go for a carddual gpu what would the min power requirements be?

ya think anyway..

Most likely the power requirements won't much different (maybe a bit lower) from requirements for sli/cf. For example for 7970 crossfire 750 W PSU is recommended http://www.guru3d.com/article/radeon-hd-7970-crossfire-review/7 . Same goes for gtx 680 sli http://www.guru3d.com/article/geforce-gtx-680-sli-review/4 . I would just wait for the actual dual-gpu cards to come out and read the reviews for more accurate requirements.
