Computer Randomly Shutting Down

[Magiconkie0_Helmet]

I have a 5760x1080 setup w/ an accessory display (4-32' monitors). I recently installed the accessory display, and after that have been having a problem with my comp randomly shutting down, but still able to boot back up. I disconnected the accessory display to see if it would still happen, and it does. I also put in a new CPU (AMD 8320) after the problems started to happen to see if that was the problem, but it still crashes randomly. My guess is that it's either the PSU that can't handle that large load or the GPU.

When the comp crashes the Red CPU LED light comes on.

Thoughts?
