Will a seasonic x650 be suffice for my system?

Sig rig. If so, can it also handle it if the CPU will be OC'ed to about ~4.5ghz + mild OC of the GPU??

Would case fans (3-5) cause any stress to the PSU? Or its just the CPU and GPU?

Yeah a whole 1.5w-4w per fan biggrin.gif

Don't worry about it, there is nothing you can do (without hardware modification) to bottom out a Seasonic 650 with a single GPU and a single CPU. You could buy 5 hard drives, 8 fans, a few light cathodes, a dvd/bd players and still be good

Not at all.

I ran my w3680 (6 core/12 thread Xeon CPU) at 4.2 GHz 1.35V with a 580 on my X650 and had zero issues even with 8+ fans. I think the 580 uses the same, if not more wattage then your 7970, and even your 2500k @ 4.5 will pull less from the wall then my W3680 at 4.2.

A good 500w unit would be enough for your build, so yes smile.gif

Thanks guys. Last question. Would I be able to crossfire, if I wanted to, in the future?

repped for everyone's input!

i think you could cross fire but im unsure. I cant see it being to bad of an issue though you may need a 750w unit. But that unit is a solid one and will more then enough hold your system

2x 7970? No.

Think of it this way:

650w PSU is perfect for a single high end and for dual low-mid end cards.

750w PSU is for dual mid-high end cards. Single is of course fine too in that case, having lots (but not too much, otherwise you're not near the rated effiency) of head room is never a bad thing.

850w and above is for dual high dual cards.

There are some exceptions, plenty of people try to squeeze in things, but generally this is what you want to follow if you don't want your PSU to sit at 90% usage constantly.
