Hey guy's since there isn't a category for power supply's I'll just drop this here...
I am planning to buy 2 extra hd 7950's...
So that will be a total of 3
I'm running an fx8350 non overclocked so will my 850x seasonic (850watt obvious) handle this?
Thanks in advance

No I would instead recommend buying a more powerful single GPU such as the R9 290X. It has much better results with your CPU and more compatible with latest games. Sell your current 7950 if its good and you are able to.

I really do like the price/performance comparisson haha so I would like to keep my 7950 and buy 1 or 2 more but my actual interest is: Can my powersupply run this?

Your power supply will be able to handle another 1 more 7950 with no problems easily.
Your PSU of 850watts is just lying on the bare minimum power requirements of 3way -crossfire 7950s + system's wattage (850w - 900w). its gonna have serious problems as the power supply unit ages, its max output will also be decreasing if your looking to use the PSU for quite some time.
It is also not recommended ( high power usage,heat issues & diminishing returns on 3way-xfire ).
As tambeshakunt said, its better to get a powerful single gpu like r9 290x and then maybe crossfire it down in the future if you need the performance.

Yes thats right. You will be on the limit of your PSU. If your cards are all at 100% load, I think your PSU will be struggling. Therefore, if you get a single 290x, you can still have the performance AND run it with your PSU. Nevertheless, as mentioned above, you can do 2 way easily. 2 way with 7950s is still a solid configuration capable of even some 4K.
