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!
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. When using differnt PSU and you want to power off the miner, be sure to disconnect all the PSU from power.
This machine is not only our most efficient ever, using less than half the energy per gigahash of the S5, but it is also our most powerful miner to enter mass production (the S5+ had a higher hashrate but was sold on a limited basis). At 0.25 joules per gigahash, this is the most efficient machine available to the bitcoin mining public.
