|16||Power connection mode||All three PCI-E ports are required topower the board. You can use one PSUto power multiple boards, but do not attempt to power one board with two PSUs.
We suggest to prevent the control board to be powered up before hash boards be
Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
PSU: A power supply unit is not included. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required. Do not connect more than one PSU to the same hashing board!
We recommend the APW7 power supply for use with the Antminer S9i. One power supply supports one Antminer S9i.
Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power. If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered.
