I ran my A3 overclocked at 930 Gh/s average for over one month with (low hardware errors under 2k/day per board)
I used 120V power on APW3++ and it worked like a charm!
Temperatures averaged around 62-65C for boards and outside room temps were between 60F-80F
I would say bitmain's PSU is stronger than it seems and does work well!
930 GH ?!?
Oh my God, you sure? What frequency you use for it? Mine are running at 550 Gh with 90-94 degrees Celsius on chips and 70-75 on boards. It's true, it's a pretty hot ambient too.
But 930 Gh.....
