Product Description: 1. Hash Rate: 13.5TH/s ±5% 2. Power Consumption: 1350W + 12% (at the wall, with APW3 ,93% efficiency, 25C ambient temp) 3. Power Efficiency: 0.1 J/GH + 12%(at the wall, with APW3 93% efficiency, 25°C ambient temp) 4. Rated Voltage: 11.60 ~13.00V 5. Chip quantity per unit: 189 x BM1387 6. Dimensions: 350mm(L)*135mm(W)*158mm(H) 7. Cooling: 2 x 12038 fan 8. Operating Temperature: 0 °C to 40 °C 9. Network Connection: Ethernet Notes: 1. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. 2. PSU: A power supply unit is included. 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! 3.Bitmain recommends the APW3+-12-1600-A3 power supply for both the S9 and S7 miner. One such PSU cannot power more than one miner. 4. 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 PCI-e connectors connected to power supply. This Antminer S9 is not only the first 16nm miner for retail use but using less than half the energy per gigahash of the S7, but it is also our most powerful miner to enter mass production . At 0.098 joules per gigahash, this is the most efficient machine available to the bitcoin mining public. The following conditions will make the warranty invalid, bitmain will not accept warranty: 1. Disassembled machine, unauthorized changes, or replacement of components. 2. Damage caused by lightning strike, voltage surge, faulty power supply, etc. 3. Burnt circuit boards or chips. 4. Damage by water, damp or corrosion.
