Greetings,
Welcome to the forum.
I am not a HP employee.
The 4GB graphics card requires a 450 watt power supply and one eight pin PCIe connector.
Your PC has a small form factor HP proprietary power supply rated @ 310 watts. You can upgrade the power supply to 400 watts (Part number-L04618-800) using HP Part Surfer (Link). But I am not aware of HP offering anything larger than 400 watts for your PC at this time.
Regards
