Yes, 750w is plenty even if you wanted to add a second GPU

Not 2 cards. Only one. R9 390's TDP is 275W, it'll go over it at loads.

Easily, that is an unbelievable power supply. You'd be fine going down to the EVGA G2 650W also to save a few bucks.

For x2 of 390, try 800w. 850w to be safe.

ok and thanks guys for the information and i will not crossfire the r9 390 will be enough for me.

That would leave about 50 watts of headroom with nothing overclocked, not nearly enough for overclocking and having only 50 watts of headroom isn't a good idea anyways.

TDP ≠ power usage
