2. Please select the correct address for shipping before you submit your order because, for this batch, the shipping address and shipping method cannot be changed after the order has been submitted.

3.The shipping for this batch will start on a first-paid-first-ship basis on 21th May 2018 for orders that Bitmain has received full payment for. We advise you to research and prepare in advance for the customs' clearance in your country to avoid delays or unexpected costs.

4.Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter.

5. 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!

6. 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 only after all the 10x PCIE connectors are connected to power supply.
