I need to replace the 310 watt PSU with a 500 watt or higher. Is that possible? I have not had any luck navigating the HP parts and supplies pages. Thanks in advance.

@wesraue , welcome to the Community.
The motherboard in your computer is HP proprietary. It has a 4-pin power connector instead of a standard 24-pin ATX power connector. You will have to buy any PSU upgrade from HP. HP has a 500W (L05757-800) PSU that is compatible with your motherboard. You can order it using HP PartSurfer: https://partsurfer.hp.com/Search.aspx?searchText=L05757-800
Just click the box under "Add to Cart" and it will add it to your cart.

All of the Erica motherboards have the same power connector.
