HP elitedesk 800 G5 DM GPU upgrade possibly external

HP Elitedesk 800 G5 mini pc (DM)
Microsoft Windows 10 (64-bit)

Hi, I got a brand new HP Elitedesk 800 G5 mini pc (DM), Core i7 9th Gen, Intel UHD Graphics 630. I’m wondering if I could connect an external graphics card. I saw some GPU casing for graphics card. I know some people can do that very easily. I want some advice. 

Same model has two version:

DM - mini pc,

SFF - small form factor (slot for graphics card)

mine is DM.

ELITEDESK 800 G5 micro form factor(MFF) does not have Graphic slot, You can not upgrade to graphics card.

The smallest graphics card is bigger then your Desktop Mini(DM). 

The GPU you saw is probably for AMD CPU those have onboard GPU chips on the motherboard.

The G5 can probably upgraded to i9-9900 CPU 65W.

If you have a G5 35W version i7-9700T you will have to upgrade power supply to 95W+ to make

i7-9700 65W CPU to work plus a chassis fan install, or else it will warn you at bootup saying a chassis

fan is not present, press ENTER to continue. With higher power CPU temperature is an issue when running

heavy CPU load. It will reach over 100*C under 100% CPU load. As long as you don't overload cpu you should have no problem. Browsing the web and watching videos online will have little effect on 65W cpu.


If your system have a PCIex16 slot and its has a small footprint, you will have to find lowprofile

graphics card for it. And then you have to upgrade your power supply to higher wattage.

For example if you have a i7-9700 65W cpu + Graphics card 125W (GTX 1660). you will need a 

200Watt plus power supply, If you have a video card that consume 250watt. You will need a 350watt

power supply. Every item you plug into your PC consumes some power (wattages). If not, your system 

will give you the blue screen of death and random crashes and reboots under load. It will refuse to boot

if you don't have enough power.
