6. The shipping for this batch will start on a first-paid-first ship basis on 11th May 2018 for orders that Bitmain has received full payment for. We advise you to research and prepare in advance for customs' clearance in your country to avoid delays or unexpected costs.

7. You will need an ATX PSU with sufficient six-pin PCIe connectors. All PCIe connectors on a hashing board need to be connected to the PSU for the hashing board to operate. Do not connect more than one PSU to the same hashing board. Bitmain recommends the APW3++ power supply to power the Antminer B3.

8. Separate power supply to control board: there will be one additional six-pin PCIe connector on the IO board which must be connected to the PSU to get power. Be sure to power on the miner only after all PCIe connectors are connected to the power supply.
