Optiplex SFF 780 PSU compatible with Optiplex SFF 790?

Question

My Optiplex 790 SFF has probably a faulty power supply (the green led does not come up), can I use a spare Optiplex 780 SFF power supply? Thanks.

Thanks for the reply. Connectors are the same, specs looks similar to me, physical dimensions are different but is not an issue. So should be ok? Thanks.

It will work just not in the slot of the old PSU.
