Can a rx550 run on my hp Compaq elite 8300?

Would a rx550 work on my pc? It has 320w psu without a 6 pin connector. I'm finding the cheapest I can get or should I get a gtx 750ti?

@Mucip , welcome to the forum.

Here is a HP Knowledge Base article that will help you.  Read the information about the BIOS/UEFI carefully.  I am not certain that your workstation has UEFI.  HP began using UEFI in mid-October, 2012.  According to the information that I found on your workstation it was released in 2012, but I don't know exactly what date.  Also, here is the Illustrated Parts and Service Map for the workstation.  Look at the section titled "Other boards" for a list of compatible video cards.

All of the RX 550 cards that I reviewed require a minimum of 400W to operate properly.  Your 320W PSU is not enough.

Am I able to change the psu with this pc?

@Mucip, HP has their motherboards and other components made to their specifications.  Therefore, the motherboards are not necessarily the same a retail boards.  I believe that your motherboard has a proprietary ATX power connector and not the standard 24-pin.  For this reason, it is difficult to find upgrades for the power supplies.
