1. Each AntMiner R4 has 6 PCI-e connectors for +12V/15A DC STABLE input on hash boards and 1 PCI-e connector on the controller, all the 7 PCI-e connectors are required. Do not connect more than one PSU to the same hash board to prevent possible damage and instability.

2. Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.

3. Power supply unit is not included. The Antminer R4 can operate with APW5 as well as the APW3 power supply unit. To get the most out of the R4, Bitmain recommends the APW5 power supply.
