Hello everybody.

I want to upgrade my graphic card on my HP Compaq Elite 8300(Microtower) .The reason i want to upgrade is to play games. Also i searched almost everywhere but i could not find my answer.
First of all i would like to know which graphic cards are compatible with my PC.
The main problem is of Power which is only available of about 320 watts. If i can upgrade my power supply how can i upgrade it?
My current rig is

Intel Core i7-3770 Processor
Intel HD Graphics 4000

I was thinking of buying NVIDIA GTX 750TI but if i can get a better graphic card that would be great.
Also if there is a way of upgrading PSU plz tell me. I also considered NVIDIA GTX 760 but that requires about 500 watts of power... So will an adapter solve my problem of so which adapter will work best?


Thanks in advance.
 
Unfortunatly that PC uses non standard motherboard and PSU, so you will be unable to upgrade the PSU without changing the motherboard (and probably case also).

The gtx 950 might work if the PSU has a 6 pin pci-e connector? If not, the 750 ti is probably the best option.
 


i am not a tech person person and i do not fully understand the connectors but this is the information taken from the manual of the PC
