It'll be close but doable.

Agreed.

For less than that price, you can get the Corsair TX850.

An excellent suggestion. Using that TT Toughpower is "pushing it" & is not recommended.

(1) If you already own the TT, use it, it will work, but outside of the ideal power envelope we prefer to provide "overhead" for OC'ing, transient response & cool/quiet operation.

(2) If buying new, get the Corsair TX850 as suggest above.

Best Wishes,
Dave
