Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. Figures provided are at the wall, with AC/DC 93% efficiency, and 25°C ambient temp. 2. PSU: A power supply unit is not included, and you will need to purchase one separately. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required on each board. Do not connect more than one PSU to the same hashing board! 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. The APW3-12-1600-B2 power supply is recommended for use with the S7 but only if you have 205v+. One of these power supplies will support one S7.
