Notes:
1. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter.
2.Power supply unit is not included.You will need an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 need to be connected to the PSU for the hashboard to operate.Do not connect more than one PSU to the same hashing board!
Bit-Winkor recommends theAPW3-12-1600-B2power supply for both the S9 and S7 miner.It cannot power more than one miner.
3. 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.Be sure to power on the miner after ALL the 10x PCIE connectors connected to power supply.
The Antminer S9 is not only the first 16nm miner for retail use but, using less than half the energy per gigahash of the S7, it is also the world's most power-efficient miner that is ready to order.7. Bit-Winkor does not take any responsibility for or compensate for any loss as result of downtime caused by delays in transportation as a result of custom formalities or other reasons.
