Just about everything in the Optiplex 780 SFF is specific to that computer. This is typical of Optiplexes in general and SFF in particular. The PSU will shut down if it detects anything wrong elsewhere in the computer. There are diagnostic LEDs in the fornt of dells that can tell what's wrong if they come on before it shuts down.

But can it have different psu

Yes and no. If you find one that fits, sure. But you might need a new case, etc. But i would bet that somethibg else in there is also broken. If it shorted the psu it mightve also damaged parts on the motherboard. Unless if you can try with another psu just to see if its worth fixing, else i wouldnt go through the trouble

It's possible to use a normal PSU as a giant wall wart. The cables are long enough to reach inside the small case either for testing or as a permamnent upgrade.

BTW I sent the PSU in a repair store for PC hopefully he fixes it if no I will tell about a different PSU but yet it need his own mark? Or could be any think like HP square?

It's the size and shape of the PSU that makes it difficult. There is an adaptor for the mini 24 pin connector.

Be sure and get one for a Dell. HP is slightly different.
i'm afraid sff is difficult to work with. If something else is damaged the PSU will detect it and shut itself off to protect the system. But maybe the computer shop can switch some parts around and find the problem.

Thanks for you help guys anyways the repair shop told me that a part on the board was burnt in the PSU and he said its hard to repair it but thanks for the idea about convertor 24 pin I will try it. Oh I have forgot to say that I put my optiplex 780 case in trash well I should not have done it but well its hard to find case now for that model thanks again guys
