4.1 Power Connections

Two power connections supply the motherboard and several more supply for onboard devices.
Main Power Connector
Two proprietary main power headers are located at PSU1 and PSU2. Connect appropriate
power supply units to these two headers to provide adequate power to your system.
Important: To provide adequate power to the motherboard, connect the both main power
connectors to the power supply. Failure to do so may void the manufacturer's warranty on
your power supply and motherboard.
Backplane Power Connectors & GPU Power Connectors
In addition to the main power headers, eight 8-pin power connectors are also located on the
motherboard to supply power to onboard devices. GPU Power Connectors 1-4 are used for
GPU devices, while BP PWR 1-4 are used for backplane devices. Connect these connectors
to your power supply to provide adequate power to your onboard devices.
