I've been using an older PSU for a while. HP 5188-2625, however it only has a 24pin and a 4pin so I cannot connect a graphics card.

I have another computer that runs fine but I do not use anymore. It has a Antec Earthwatts EA-500D Green PSU.

When I replace the HP 5188-2625 with the antec PSU, my fan starts for 1 second, then stops.
I thought I may have broken something, so I put both the PSU back to their original computers, and both works fine.

All components are not broken, because they are working fine in their original computers.

Note: both psu are 24pin and 4pin(for CPU)

Does anyone know the problem or fixes?
