Notes -
Old power supplies can still be useful as spare benchtop equipment, if you do any electrical engineering or 3d printing. They can't be trusted for their rated amperage at that age, but there's a lot of applications where you just need 10~20 amps at 12v and don't really care if it's a little noisy. To turn on without a motherboard, simply disconnect the power wire, short the 24-pin green wire to any black wire, and check that no other wires are shorted, and reconnect power.
That said, it's competing against a 20-buck Amazon buy, so if you don't have a use case, probably not worth your time to sell.
