Prodesk 400 G4 into Gaming Machine

[Sahib_212]

Hlo, I just want to know if by any mean I can turn my HP Prodesk 400 G4 i5-6500T variant into gaming machine,I want to play new games like WWE 2k24 ,Hogwarts Legacy. Should I upgrade this or sell it.

• GPU- low profile gpus are too expensive for me, can I install full size card into it without destroying it. I want cards like RX580 or GTX 1660
• PROCESSOR- Can I upgrade its processors to later generations I want to run windows 11 in it.
• SSD- Can I add 500 gb ssd 
• PSU- Will I need to use another psu for it.

@Sahib_212,

Welcome to our HP community forum!

If you are referring to an HP ProDesk 400 G4 Desktop Mini (DM) :

Upgrading this DM into a gaming platform isn't practical. Reason being is that a Desktop Mini (DM) doesn't have a PCIe graphics slot.  Now, there are ways around this if you are a hardcore hobbyist.  As you can see in my HP EliteDesk 800 65W G4 Mini (DM) upgrade project, but it would be expensive and labor intensive: Solved: Upgrading an HP EliteDesk 800 65W G4 Desktop Mini (DM) - HP Support Community - 8708671, where I utilized an M.2 NVMe SSD slot to plug in a "PCIe 4.0 x4 Riser Cable 64Gbs M.2 Key M for NVMe External Graphics Card" adapter in order to install an external graphics card powered by an external synced ATX power supply.

If you got an HP ProDesk 400 G4 SFF (Small Form Factor), this too was one of my upgrade projects. The problem is that there are no power supply upgrades available beyond the stock 180-watt power supply, so you'll have to sync an ATX power supply like I did (see link) in order to power a decent graphics card.  An RX 580 requires a 500-watt PSU, and a GTX 1660 requires at least a 300-watt PSU.

And no, the best processor that is compatible with an HP ProDesk 400 G4 would be an i7-7700K, which is not Windows 11 eligible, but there are ways around that too, if you're interested.

You can install any capacity 2.5" SATA SSD and/or an M.2 NVMe SSD drive.

Either way, you should probably sell your HP ProDesk 400 G4.

Hope this was helpful.
