[QUOTE="harryb2448, post: 1586291, member: 42497"] Sounds like dead power supply. Only option if that is correct, replacement needed. Also some models have a fuse which can blow. Another suggestion, any chance you are using the Mac Pro with a circuit breaker? If so try without the breaker, and also change the power lead. And what model UPS? I use an iBox with my iMac but for a MAc Pro much stronger unit needed. Tried disconnecting the UPS? [/QUOTE]
