*POWER SUPPLY IS NOT INCLUDED*
Bitmain recommends using the APW3++ or APW7 power supply.

AntMiner V9 Specifications:

• Hash Rate: 4.0 TH/s (within 5%)
• Power Consumption: 1027W (within 10% at the wall, with APW3++, 93% efficiency, 25C ambient temp)
• Power Efficiency: 0.253 W/GH (within 7% at the wall, with APW3++, 93% efficiency, 25?C ambient temp)
• Rated Voltage: 11.60 ~13.00V
• ASIC Chip: BM1580
• Dimensions: 301mm(L)*123mm(W)*155mm(H)
• Cooling: 2x 12038 fans
• Operating Temperature: 0C to 40C
• Network Connection: Ethernet (network cable not included)

Please note the following:

• Each AntMiner V9 requires TEN 6-pin PCI-e connectors for 12V DC input (must be very stable power source). There are three hash boards that each require THREE 6-pin PCI-e power connectors and one additional 6-pin PCI-e power connector on the controller. All TEN 6-pin PCI-e power connectors are required. Do not connect more than one PSU to the same hash board to prevent possible damage and instability. 
• Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. 
• The power supply unit is not included. Bitmain recommends the APW3++ power supply for the AntMiner V9.
