I am trying to find if there are any available power supply upgrades for my Pavillion 590-p0xxx. I upgraded it from a Ryzen 3 (that came in it) to a Ryzan 5, with no issues. When purchased it had no graphics card. I recently purchased an AMD Radeon RX 5500 XT and it fit in with no problems, downloaded drivers, etc. But now it looks like it needs something called a pcie connection. I looked into build photos and shows an extra cord plugged into it, which I assume powers the card. After looking for a bit, my pc doesn't have this needed cord. So is it safe to assume I require a different power supply? Any help is apprecited. Thanks, David
What is the Product Number of the computer? I need this information to review the specifications of it. Please don't furnish the Serial # or other personal information. You can find the Product Number at the bottom of the page when you open HP Support Assistant.
Any of the HP 590 series computers utilize an HP proprietary designed power (PSU) supply. The proper wattage would be a 400W model L04618-800, ordered from HP Parts Store.
