1. Specifications of the Antminer D3 are as follows: A) Hash rate: 15 GH/s (Variation of 5 percent is expected) B) Power consumption: 1200W (at the wall, with Bitmain's APW3 PSU, 93 percent efficiency, 25C ambient temp). C) Hashing algorithm: X11 2. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. 3. It recommends use of the APW3 plus plus PSU with the Antminer D3. One APW3 plus plus PSU can not power more than one Antminer D3. 4. All PCIe connectors on a hashing board need to be connected to the PSU for the hash board to operate. Do not connect more than one PSU to the same hashing board. 5. Separate power supply to control board: There is one additional 6pin 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 PCIE connectors are connected to power supply.
