Bitmain is pleased to introduce our latest machine, the Antminer S7. This powerful machine features a small form factor, like our previous Antminer S5, while utilizing the denser hash board arrangement of the more recent S5+. This is the first Bitmain product to use our recently announced BM1385 chip, which is not only more than twice as power efficient as the BM1384 chip before it, but is also the most power efficient chip available to consumers today. 

The Antminer S7 has a more dense configuration than previous Antminer machines, using 145 chips in the same space that the S5 used only 60 in. The S7 uses just 1042 watts of electricity to deliver a whopping 4.05 terahashes per second of pure mining power.

S7 Specifications:

1. Hash Rate: 4.73 TH/s ±5%

2. Power Consumption: 1250 W (at the wall, with AC/DC 93% efficiency, 25C ambient temp)

3. Power Efficiency: 0.25 J/GH (at the wall, with AC/DC 93% efficiency, 25°C ambient temp)

4.  Rated Voltage: 11.60 ~ 13.00V

5. Chip quantity per unit: 145x BM1385

6. Dimensions: 301mm(L)*123mm(W)*155mm(H)

7. Cooling: 2x 12038 fan

8. Operating Temperature: 0 °C to 40 °C

9. Default Frequency: 700M

10. 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 not included, and you will need to provide an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required. Do not connect more than one PSU to the same hashing board! PSU Link :ANTMINER 1600w PSU,this is good PSU

Bitmain recommends the APW3-12-1600-B2 power supply for use with the S7. One power supply support one S7.

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. If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered
