Hey,

I have 2 Mac Pro 8 core. One of them sudden shuts down. If I open skype it automaticly shut down. If i run geekbench it shutdown immediately.

I tried a lot of things with no success. I installed istat menus 4 in my both same Mac Pro... All the values are almost the same, same temperatures, etc. The difference I notice was in "PSMI SUPPLY AC/DC output". One shows about 11-12 A on idle and stays constant beetween this values. The other that shut down is about 6-8-10, it isn't stable like the other. When I run geekbench the Mac Pro who sudden shut down goes about 12A and it shut down, the one is working well goes to 20A with no problem.

Someone knows what it means?
This problem is annoying me a lot. I already bring computer on apple shop and after 15 days they say computer is ok and having nothing wrong. I tried remove ram, format drive, etc etc

Thks in advance.
 
Hi jump!
I think that is exactly my problem. Did you replace your PSU?
