@KBest002,

Welcome to our HP User Forum!

Your HP Pavilion 590-P0050 (3LA16AA), according to: https://support.hp.com/us-en/document/c06000982, is fitted with the Lincs motherboard (SSID: 843B), and a 310-watt power supply.

If you are uninclined to upgrade your power supply, here are some graphics card options: Nvidia GeForce GTX 1050 Ti 4GB, MSI GeForce GTX 1650 Low-Profile Dual Fan 4GB, and the Nvidia RTX A2000 6GB.

However, there is a 400-watt power supply upgrade available, according to: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model...: with HP p/n: L04618-800:

And possibly also a 500-watt power supply (HP p/n: L05757-800).

These power supplies can be purchased via eBay or other online eCommerce sites.

Either one of these PSU upgrades would vastly expand your GPU choices.

Regardless of what graphics card you pick, carefully check its dimensions -especially height and length, for fit inside your case.

Kind Regards,
