@Saprophyte2 , welcome back to the Community.
It appears from looking at the "Interactive Part Locator", in the Manuals section of the specifications, that the PSU is very close to the M.2 socket. Therefore, you have to assure that the measurements of the one you choose is very close to the same size as the current PSU. Otherwise, you should be able to use any standard ATX PSU. The power connector on the motherboard is the standard 24-pin connector.
