Good to go?

This is the build that i came up with with the help of users on this forum. 

I plan on using only one 7970 for the time being. 

My question is regarding the PSU and one card. is this sufficient while I get the second card?

Will The PSU be just fine for now even if I don't get the second one?

Are there alternatives? this psu is a combo deal.

Not planning on getting the new AMD hawaii gpus anytime soon.


probably yeah ;)

From what I can see that looks like it could take 2 7970s without much problem
