Yes and yes although it would be a bit tight and you'd want more headroom. 

A decent 600w is plenty for a single 290.

Is a 750w overkill for a single gpu set up? Im planning to use a R9 290 Tri-X and do some OC'ing in a 4670k. Is 750w also enough for a 290 crossfire?

So for a crossfire config a 850w PSU is better?

For two GTX 780's, 750W is more than enough for any build. I'm not sure how much more power the AMD cards sip so based off this I'd say 750W would be plenty.

CPU: 5930K @ 4.5GHz | GPU: Zotac GTX 980Ti AMP! Extreme edition @ 1503MHz/7400MHz | RAM: 16GB Corsair Dom Plat @ 2667MHz CAS 13 | Motherboard: Asus X99 Sabertooth | Boot Drive: 400GB Intel 750 Series NVMe SSD | PSU: Corsair HX1000i | Monitor: Dell U2713HM 1440p monitor
