Product: HP ProDesk 400 G5 MT

Hey there. I just ordered this PC and as I'm waiting for it to arrive I want to buy the parts neccesary for it. It's gonna be first computer that I can game on and im hoping to atleast keep it for a while

Now; back onto the topic. I want to put a rx580 8gb into it; is there any power supply unit with same connectors as to the original one in it where i can replace and have 6 pin/ 8 or 6 +2 pin for GPU? It needs to be 400-500 watts for longevity 


Thanks in advance

Hello @PrebuiltPropheC, Welcome to the HP Support Community.

Congratulations on your new HP ProDesk 400 G5 MT. We understand you're looking to upgrade the system with an AMD RX 580 8GB graphics card and would like to know whether a higher-wattage power supply can be installed while maintaining compatibility with the system.
 

According to the HP ProDesk 400 G5 MT Maintenance and Service Guide, the highest power supply option officially provided for this model is a 310W, 12V, high-efficiency power supply. The service guide lists power supply options of 180W, 250W, and 310W, with no HP-supported 400W or 500W PSU for this device.


 

Please check the user guide (page 4) - Maintenance and Service Guide HP ProDesk 400 G5 MT

Have a great day!

I'm an HP Employee.
