Hi, I'm looking at upgrading the PSU and adding a graphics card to this desktop. I was wondering what are compatible 500w power supplies for this rig and what size graphics card will fit? Would a 50 series Nvidia be compatible? Thanks

Welcome to our HP Community forum!
Your HP Pavilion Desktop TP01-2234 is highly upgradeable.
there are two power supply upgrades available for you:
500-watt with p/n: L77487-003 / 901759-013 / L89233-001
650-watt with p/n: L57253-003 / L36049-003
Most smaller-sized (dual fan) RTX 40X0 and RTX 50X0 GPUs will fit in your PC.
Giving you some ideas how far you can upgrade an HP Pavilion TP01 platform, take a look at my HP Pavilion TP01-3xxx upgrade project: Solved: Upgrading an HP Pavilion TP01-3003W (318K3AA) - HP Support Community - 9254350.
