I have a Mac Pro 1,1. It has been a tough work horse. Yesterday it shut itself down. I thought nothing of it. Today it won't start. No lights, no sound... nothing. Plugged it into a different power source. Nothing. Should I replace the power supply?


Ken, that would be my first move.


Also if your experienced enough, it sounds like the caps are bad. You can replace them for only a few dollars and it will be good and working if that was the issue.


@cam2363 What was said to make you believe the caps are bad? What caps, where?


Im not sure @mayer mayer

Ive never owned a mac pro, much less seen the inside much less seen the inside of a psu. Normally when a psu fails randomly, i find that there are normally bad caps. If thats the case, bad caps are MUCH cheaper then a new psu in almost every single case.
