Hey,Sounds like a power management issue to me, the R9 280X shouldn't need that much when idling. Currently I can't verify it, but I'm quite sure my R9 280 doesn't draw more than ~20W when idling (measured by internal PSU readings from classic Mac Pro).
I see you're using r9 280 gpu. I'm having issues setting it up in Sierra. Did you have any issues similar? Looking for a solution because my system won't boot with the card.
