*POWER SUPPLY IS NOT INCLUDED* <br> If you have 220v-264v power, then Bitmain recommends using the APW3++ power supply. <br> If you have 110v-120v power (standard power outlets in the US), then the following power supplies have been confirmed to work well: EVGA's SuperNova 1600G2 <br> <br> AntMiner S9 Specifications:<br>1. Hash Rate: 14.0 TH/s ±5%<br>2. Power Consumption: 1373W ±10% (at the wall, with APW3++, 93% efficiency, 25C ambient temp)<br>3. Power Efficiency: 0.098 W/GH ±7%(at the wall, with APW3++, 93% efficiency, 25°C ambient temp)<br>4. Rated Voltage: 11.60 ~13.00V<br>5. ASIC Chip: 189 x BM1387<br>6. Dimensions: 350mm(L)*135mm(W)*158mm(H)<br>7. Cooling: 2x 12038 fans<br>8. Operating Temperature: 0 °C to 40 °C<br>9. Network Connection: Ethernet (network cable not included)<br><br>Please note the following:<br>1. Due to the nature of these products, there are higher than normal restocking fees (typically 40%). The restocking fees are typically waived in the event that there is a provable failure within the first 30 days and the warranty has not been voided by overclocking. In the event that you experience a failure, please reach out to the seller immediately so that we can begin troubleshooting with you and/or processing a return.<br>2. Each AntMiner S9 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. <br> 3. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. <br> 4. Power supply unit is not included. Bitmain recommends the APW3++ or the APW7 power supply for the AntMiner S9.
