I calculated a system in coolermasters psu calculator.
It recommended 650w for dual r9 290 and xeon e3 1230v3, one hdd and 2sticks of ddr3 ram.

Now i dont trust getting only just enough, but would a 750w be enough? Currently looking at xfx's proseries xxx edition powersupplies.

I will be adding the second r9 290 maybe (might not even do it) a year or two down the road.
I do not own any of these parts yet. I will do the build in the summer.

XFX XXX 750W is top notch and will be sufficient.

But lets say i added a wifi card, and a sound card(which i wont). and then some extra fans. Would it still be sufficient?

I am not overclocking since the xeon cannot be overclocked. Might overclock the graphics card though.
Fine as long as i'm gaming. Lets say i stress test them. Would the psu still be fine?

Compatibility between PSU and GPU are determined by its 12V rail amperage.
A = W/V
41.08 = 493/12
