Each AntMiner S9 requires TEN 6-pin PCI-e connectors for 12V DC input (must be very stable power source) There are three hash boards that require three 6-pin PCI-e connectors each and one additional 6-pin PCI-e connector on the controller. All TEN 6-pin PCI-e connectors are required. Do not connect more than one PSU to the same hash board to prevent possible damage and instability. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter.
