I am currently running this setup:

Everything runs stock at the moment.
- i7 4930K (Corsair h110 liquid cooler)
- MSI x79a gd45 plus (mobo)
- Corsair Vengeance (2x8gb) 1600mhz CL10 (RAM)
- Samsung 840 SSD 250gb
- Seagate Barracuda 2tb 7200rpm
- 1 * ASUS GTX780 direct cu ii oc
- Coolermaster v850 Vanguard Series (850w PSU)

Will i be able to put another GTX780 in SLI on that PSU?
Will i have room (with 2 gtx780's in SLI) for CPU OC'ng (in the future) / maybe another SSD / HDD / More RAM?

No, it will not handle it. You should get a 1200w PSU.

I suppose it can handle
1 gtx 780 needs maximum 250W so for 2 its 500W. remaining 350W, which can easily handle remaining stuff like processor,etc.
I had msi gtx 780 and i7 3770 on a 450W PSU and played bf4 on ultra and never faced any issues regarding power.
So i suggest no need to upgrade....

1200 Watts is seriously overkill. 850W is just about right for a rig like this. Yup, not needed to swap out.

It's more of an upgrade i'd like to do by the end of the year when the price has dropped a bit. I also don't have any performance issues right now but it's more of an upgrade to do to ensure it can still perform at the lvl i expect in about 3/4 years. I use this pc for both work / gaming so it's almost on 24/7 and mostly on high load when i work.

Should be ok as long as you don't try to overclock the GPUs, that will push the power usage through the roof.
