Power Connectors

The main power supply connection uses an SSI-compliant 2x12 pin connector (J1K3).
Three additional power-related connectors also exist:
Two SSI-compliant 2x4 pin power connectors (J9A1, J9K1) to provide 12-V power to the
CPU voltage regulators and memory.
One SSI-compliant 1x5 pin connector (J9K2) to provide I
supply.
The following tables define these connector pin-outs.
