Hi @DessyWizard,
Welcome to the HP Support Community.
I'd be happy to help you!
Upgrading the power supply unit (PSU) in your HP Pavilion 590-p0632ng to a higher wattage unit like a 500W PSU is a good idea if you're planning to upgrade components such as the graphics card. Here are the steps and considerations to ensure compatibility and a successful upgrade:
Steps to Upgrade the PSU
Check Physical Dimensions:
- Ensure the new PSU physically fits inside your case. The HP Pavilion 590-p0632ng typically uses a standard ATX PSU, so most ATX PSUs should fit.
- Measure the dimensions of your current PSU and compare them with the dimensions of the new PSU.
Check Connectors:
- Verify that the new PSU has the required connectors for your motherboard, CPU, graphics card, and other peripherals.
- You will typically need:
- A 24-pin ATX connector for the motherboard.
- A 4+4 pin CPU connector.
- PCIe connectors (6+2 pin) for your graphics card.
- SATA connectors for your drives.
Choose a Reliable PSU:
- Choose a PSU from a reputable brand (e.g., Corsair, EVGA, Seasonic) with good reviews.
- Ensure the PSU has an 80 Plus certification (e.g., Bronze, Silver, Gold) for better efficiency and reliability.
Installing the New PSU
Turn Off and Unplug Your Computer:
- Ensure your computer is turned off and unplugged from the power source.
Open the Case:
- Remove the side panel of your desktop case to access the internal components.
Disconnect the Old PSU:
- Carefully disconnect all the power cables from the motherboard, CPU, graphics card, drives, and other components.
- Unscrew and remove the old PSU from the case.
Install the New PSU:
- Insert the new PSU into the case and secure it with screws.
- Connect the new PSU cables to the motherboard, CPU, graphics card, drives, and other peripherals. Ensure all connections are secure.
Close the Case and Test:
- Replace the side panel of your case.
- Plug in your computer and turn it on.
- Verify that your computer powers on and that all components are receiving power.
Compatibility Considerations
- Power Requirements: Ensure the new PSU meets the power requirements of your upgraded components. A 500W PSU is usually sufficient for mid-range graphics cards and additional peripherals.
- Cable Management: Properly manage the cables to ensure good airflow within the case.
- Warranty: Check if upgrading the PSU affects your warranty status
By following these steps, you should be able to upgrade your HP Pavilion 590-p0632ng's PSU to a 500W unit successfully. If you have any specific questions or run into issues during the upgrade, I recommend you contact phone support.
Hope this helps! Keep me posted for further assistance.
