1. Specifications of the Antminer D3 are as follows: a) Hash rate: 15 GH/s (Variation of ±5% is expected) b) Power consumption: 1200W (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temp). c) Dimensions of the miner: 320*130*190mm d) 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. Bitmain recommends use of the APW3++ PSU with the Antminer D3. One APW3++ PSU can not power more than one Antminer D3.
