Antminer A3 (Shipping:March 15-22)


1. Specifications and other information of the Antminer A3 are as mentioned below.

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

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

4.The shipping for this batch will start on a first-order-first-ship basis on 15-22 March 2018. We advise you to research and prepare in advance for customs' clearance in your country to avoid delays or unexpected costs.

5. You will need an ATX PSU with at least 10 six-pin PCIe connectors. There are 3 six-pin PCIe connectors on each hashing board and all three 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++ to power the A3.

6. Separate power supply to control board: there is 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 the 10 PCIe connectors are connected to a power supply.
