Which graphics card can i install in my pc?

Hi, i was wondering which graphics card could i install in my pc, i need to know the motherboard power and i´m not able to find this anywhere. I also need to know if this computer has got the 6-pin connection for the graphics card. I read that the psu is 200w, but i saw that it can run a GT730 (which nvidia reccomends to have a 350w psu), so i´m a bit confused. Could i install for example a GTX950 or a RX460?

Thanks!
