Replacing power supply on Imac

Mi Problema

The Imac was randomly restarting itself after a few minutes of being on, research told me that power supply might be the issue

Mi Solución

I exchanged the part but the imac still has the same issue. It is not related to over heating because temperatures read normal. I think the issue might be the logic board which is too expensive to replace without being certain.

Mi Consejo

Trial and error, you win some... you loose some. Might now sell it for parts.
