it does two volts. 12 directly to the controller and about 20 to the boards the board power will vary down to 16 maybe less. say 14.

hi, the APW9 and APW9 + PSUs, so for ALL bitmain 17 series, start like this:

directly to the connection of the 2 cables C13, PCIE out directly + 12V

and only after, the firmware power up the 2nd power (14v - 21v)
