HP Elitedesk G5 Mini GPU help (RX560)

[Keem312]

Hello, I saw that my G5 Mini had an option to upgrade the GPU to the AMD RX 560 (discrete card). I installed the unit but it doesn't seem to have power or not being recognized by my system. 

I'm wondering if I have a missing  motherboard slot or if my power adapter needs to be upgraded to give it enough power. I currently have a 90W power adapter. I noticed a few teardown videos on YouTube shows a motherboard slot but some do not. Any help would be appreciated.

@Keem312,

If you had an HP EliteDesk 800 G5 Desktop Mini (DM), your motherboard (p/n: L54553-001 "SPS-MBD 800G5DM CFL-Q370 35W") with SSID: 8595, should look like this:

Reference: HP PartSurfer

However, you do not have an HP EliteDesk 800 G5 DM, but an HP EliteDesk 800 G4 DM, which is not compatible with the RX 560 graphics card:

Not to worry per se: you can still upgrade your DM's graphics capabilities, but not as easy or as inexpensive as my recent HP EliteDesk 800 G4 DM upgrade project shows: Solved: Upgrading an HP EliteDesk 800 65W G4 Desktop Mini (DM) - HP Support Community - 8708671.

Hope this was helpful.

Thanks for the reply, very strange because I definitely have a G5 as confirmed by the serial number and system information (see image).

@Keem312,

My bad: I stand corrected -indeed, you got an HP EliteDesk 800 G5 DM motherboard, with p/n:  L54551-001 "SPS-MBD 800G5DM CFL-Q370 65W":

Nevertheless, the same graphics restriction applies though: the GPU slot is missing on this G5 DM model motherboard compared with the G5 DM motherboard Baseboard Product 8595...

After some tracking down, the specific part is labeled 'j41 mxm' slot. Seems like a proprietary slot to fit the discrete AMD RX560 card specifically made for this mini pc. I can solder the piece on myself but finding it will be a struggle.

@Keem312,

Given the headaches involved with finding a spare J41 MXM slot (unlikely), then soldering it in place (nigh impossible, trust me), and then hoping your motherboard will actually accept/recognize it (iffy at best), seems to me that your best/easiest approach is to swap motherboards -here is an affordable SSID 8595 motherboard purchase option for just $68 from a "top-rated plus" (trusted) eBay Seller: HP Motherboard L52071-001 | No CPU | eBay.

@Keem312,

Looks like an HP RX 560 4GB graphics card/heatsink/cooling fan combo (p/n: L21466-001) doesn't come cheap: the lowest pricing I found via eBay was $142:

So, if it was the case that you spend around that much for your RX 560, the additional motherboard expenditure would be worth-it, IMO.

Thanks for the find, wow it's becoming a much bigger headache than I realized. The Rx560 is already about 7 years old but I thought it would be convenient to have a mini pc to play a couple games on the family computer.

I actually have a more powerful PC in storage that I can just plug and play a new GPU. The PC is pretty bulky but I might dust it off and just hide it under the desk lol.

Thanks for the help again. I caved in and ordered that motherboard since you can't beat that price! I'll just transfer everything to the new board and get a new 150w power supply to comfortably handle the CPU and GPU.

@Keem312,

A 150-watt power charger would likely work, but if you are going to buy one of those, I would recommend a 230-watt power charger with p/n: 677765-001, like I used for my G3/G4-DM upgrade projects.

You can purchase one of these for less than $20 via eBay. It is better to err on the side of caution having more wattage under the hood, so to speak.
