GPU Power Connectors
Three power connectors for GPU and VGA devices are located at JGPW1, JGPW2,
and JGPW3. Connect an appropriate cable to each GPU power connector to provide
power for your GPU/VGA devices.
Power Connectors
Two SMCI-proprietary power supply units (PSU1/PSU2) are located on the moth-
erboard to provide main power supply to your system. Additionally, three 8-pin
backplane power connectors (JPW1/JPW2/JPW3) are used to provide power to
the backplane devices. See the table below for pin definitions.
