Bitmain AntMiner R4 8.00 THs Notes:
1. Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
2. Power supply unit is not included. You will need an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 need to be connected to the PSU for the hashboard to operate. 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. Be sure to power on the miner after ALL the 10x PCIE connectors connected to power supply.
