I have a 780 ti and a 650 watt psu and its perfectly fine. The 290x uses 50 more watts so it might be cutting it close. put all your parts in pc part picker and it will tell you an estimate of the most watts it will use.

I will go with xfx 850 watt

Becous the xfx 650watt (62€) & 750watt (67€) & 850watt(66€)
I don't know why the 850 watt chapper

650w is more than enough for a single 280x. That 650w xfx would be fine for a 290x aswell. the 850w XFX would be enough to crossfire 2 280X's but if it's cheaper than the 650w one, why not.

 

[PingedMoon]

The 850w price is a good deal
is chaper than 750w

Now what about the motherbored?

Depends on how much overclocking you want to do. That 970 is a good board and should allow for a decent OC. The 990fx is usually a better overclocker, but not by much(in this case) as they both have an 8+2 vrm phase.
