Can I upgrade the video card in my OMEN Obelisk Desktop 875-0xxx?

[Oldguy53]

I have an OMEN by HP Obelisk Desktop 875-0xxx.

Is the video card upgradeable?  If so, are there limits?

Welcome to the HP Forum.

There are two general graphics card upgrade limits.

1. Discrete graphics card dimensions

2. Power supply wattage

875-0xxx is generic. Please provide a specific HP Product Number or check your HP power supply for wattage and GPU PCIe power connectors. Then get back to the Forum with power supply specs.(preferred).

You would need at least one six plus two pin PCIe connector for most mid range graphics cards.

Your PC's case can probably handle about a 10 inch dual slot, dual fan graphics card.

You can upgrade the installed power supply, if needed, using standard ATX power supplies.

The HP Product number is 4NN77AA#ABA.

Thank you for the additional info.

HP PC Support sites providing technical information have been very unreliable recently. I did find specifications for your PC at a third party reseller. The document is Here.

Your PC has:

- A dual slot Nvidia 1660 at 9 inches in length which should require one 8 pin PCIe power supply connection.

HP has some components made to their specs. So your 1660 may vary. Measure: your 1660 to verify dimensions and available room in the PC case.

- A 500 watt ATX power supply. This power supply should have, at least one 6+2 pin PCIe power connector for supplemental graphics card power. This power supply may have a second 6+2 pin connector. Examine the HP power supply to verify available PCIe connectors.

Check this YouTube video for many graphics cards that should work with your PC's case and power supply. The HP PC in the video is not your product but the case has similar space limitations.

And your PC's power supply, unlike the power supply installed in the TG01 PC in the video, can be upgraded, if desired,  using standard ATX power supplies.

Open the "more" option below the video for links to online retailers and current graphics card pricing.
