Not enough, a 1000W unit like the EVGA SuperNOVA G2 1000W is recommended.

If you plan to crossfire. It may be fine but not enough headroom. I recommend at least 800W. :)

It'll cut it close with that OC'ed CPU.

The RM750 is okay, but it's made by Channel Well Technology. (Channel Well Trash). Bad capacitors and it's overpriced.
Enjoy! :)

a single sapphire tri z uses 419 at max, so double that, leaves us at 838, a 1000w or more is needed, 750 is no where near enough

419 including other components. 750W would work and 850W is plenty. Although if you can afford the G2 1000W, go for it. :)

The AX760 is good, but it's underpowered for R9 290 CrossFire.
