The world’s first bitcoin mining ASIC based on the 16nm process node Bitmain’s BM1387 chip is built using TSMC’s 16nm FinFET technology and, delivering a record-breaking 0.098 J/GHs, is the world’s most efficient bitcoin mining chip in the consumer market. Each Antminer S9 employs 189 such chips to deliver more hashrate and efficiency than any bitcoin miner ever made. Specification Hash rate: 14TH/s (±5%) Power consumption: 1372W Power Efficiency: 0.098 J/GH (+10%) Rated Voltage: 11.60~13.00V Chip quantity per unit: 189x BM1387 Dimensions of the miner: 350x135x158 mm Cooling: 6000rpm front fan, 4300rpm rear fan Operating Temperature: 0°C to 40°C Network Connection: Ethernet Frequency: Automatically set Notes 1. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. 2. Power supply unit is not included. You will need an ATX PSU. 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! Bitmain recommends the APW3-12-1600-B2 power supply for both the S9 and S7 miner. It cannot power more than one miner. 3. 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 after ALL the 10x PCIE connectors connected to power supply.
