4.1 Power Connections
Power Supply Unit Connectors
Two main power supply unit connectors (PSU1/PSU2) are located on J24/J25 on the
motherboard. Connect these connectors to your power supply to provide power to your
system. See the layout drawing below for the locations of PSU1 and PSU2.
12V 8-pin CPU Power Connectors
In addition to the main power supply units, there are seven 8-pin 12V DC power connectors
located on the motherboard. Four of these 8-pin power connectors (JPWR1-JPWR4) are
used for GPU devices, and the remaining three (JPWR5-JPWR7) are used for backplane
devices. Additionally, J12VSB, located between PSU1/PSU2, provides 12V standby power
to the system. Refer to the table below for pin definitions.
