What? 781 watts for one single? What am I seeing here?
Sorry, not electrical savvy. You should change your thread title to 180GH since you are showing 3 Singles.
No, that's 781W for 3 SC Singles. We're not talking about Avalon units.

Thanks for posting. That means one PSU in an MR that handles four of the eight Singles will run 1041w roughly.
Can you record a video? I'd like to watch the +/- 10% variance on your kill-a-watt if I could.
