What Graphics card can I use with a HP Prodesk 400 G6 MT?

[Saft_Chri]

I have this computer and the integrated graphics (Intel UHD Graphocs 630) don’t work that well with games. Do I have some options to upgrade the graphics card?

CPU: Intel i7-9700

16 GB RAM

@Saft_Chri,

According to HP's specs of your Microtower (HP ProDesk 400 G6 Microtower Business PC Specifications | HP® Customer Support), your power supply is either a 180 (most likely), 250 or 310 watt unit -please verify.

Regardless, this limits your GPU options.

I would recommend a low power (which happens to be also low profile) MSI NVIDIA GeForce GTX 1650 4GT, such as here: Amazon.com: MSI NVIDIA GeForce GTX 1650 4GT LP 4GB GDDR5 HDMI/DL-DVI-D PCI-Express Video Card : Elec... which doesn't require a 6/8-pin PCIe power connection.  Draws all the power it needs from your PCIe X16 slot.

With this caveat: looking at a picture of your "SPS-BD SYS ProDesk 400 G6 MT Win" motherboard (HP p/n: L64052-601), there could be a potential GPU fitting/space issue with your RAM modules -see blue rounded rectangle for your PCIe X16 slot, and the red arrow pointing to your RAM slots.  I think you should be OK, but I just want to mention it.

Hope this helps.

Kind Regards,
