Anyone heard of a Mac Pro tripping a breaker when powered on?

[lokiju]

I have two Mac Pro's in my house. The first one I got would always trip the circuit breaker in my office almost every time I turned it on but I just always assumed it was due to wiring in my office. Then I got a second one and when I was setting it up it was down in my living room at the time and it never tripped a circuit. Then I moved that one into my office and removed the other one that had been tripping circuits and the new one has never once tripped a circuit plugged into the same outlet as the old one did.

I then moved the circuit tripping Mac Pro to my living room and reloaded the OS and in the process tripped a circuit turning it on. I got it all built up and moved it to my bedroom and every time it comes out of sleep or gets turned on it usually trips the circuit.

What in the hell is going on with this thing?

Is this a known issue with the 2.66ghz Intel Xeon Mac Pros? If so, is there some kind of fix?

2.66GHz intel Xeon G5 Mac Pro.... one of these things is not like the other....

Is it a Mac Pro or a PowerMac, is it a Xeon or a G5? If you pull the side off and G5 is laser etched onto the heatsinks, that would be your first clue. I don't think that the PowerMac G5 had a 2.66 model, I think it was a 2.5 and a 2.7(5?) but no 2.66, so that to me says Xeon.

It could be a bad power supply, if it is trippin' circuits all over da house then it is definitely isolated to the Mac Pro. When you moved the bad Mac Pro around, what else moved with it?

Guess it's not a G5.

This is the one.
