D.11 Motherboard Bus Bar Power Connectors

Main power is delivered to the motherboard through bus bar connectors that also attach to the power distribution board. There are two connector strips that attach to the mother board with six bus bar screws to provide +12V and ground. See Motherboard Bus Bar Connector for the location of the connector strips under the motherboard.
