    Hey everyone, i have been a very happy Mac Pro 4,1 owner for almost a month now or so and have completed some upgrades such a a GTX 680 flashed for Mac, 512GB SSD for boot, 32GB of ram, and a nice triple monitor setup :) ....Now the problem, while listening to youtube last night my Mac suddenly rebooted and in the console log i dug up this:

    Anyone have any insight or experience with this issue?

    Though I am not sure what the console log indicates, it might be a power supply issue. Before in our office we had an iMac that would reboot by itself at random and it was traced to a faulty power supply. The power supply was replaced and the iMac was working fine after that. Try to observe further if this rebooting would repeatedly occur. That's a nice Mac Pro as I have used that machine.

    Are you using ECC RAM now?

    Non ECC RAM won't cause the problem, but it can rule out if that's the RAM's problem.
