Interesting work. Did you use the stock controller?

so 40th and about ? watts

Thanks! 3800 W for power usage and yes, it's stock controller but I added three more ports to the board.

So these are basically 6 boards from 2x S9j miners, right?

They are antminer s9i boards, it will work is s9j as well.

No, they are not s9 hydro boards, I am waiting for that to see what's inside.
