I think that has 52A on the 12v rail (which is comparable to the corasir/antec/seasonic 650W units).

But yeah, that psu is fine.

you're fine. the only trouble i can see is if you wanted to add a custom water loop with 2 rads and tons of fans and controller. but 700w can run that as well. you're fine
