Motherboard Connections
This section describes the connections on the motherboard and provides pinout definitions.
Note that depending on how the system is configured, not all connections are required.
The LEDs on the motherboard are also described here. A motherboard layout indicating
component locations may be found in Chapter 1.
Please review the Safety Precautions in Appendix B before installing or removing components.
4.1 Power Connections
There are several different power connectors on the X11DPU-V as described below.
•
SMCI-proprietary Power Connectors (PSU1/PSU2)
•
8-pin HDD Backplane Power Connectors (BP PWR 1/2/3/4)
SMCI-Propietary Main Power Supply Units
Two SMCI-proprietary main power supply units are located at PSU1 and PSU2. Connect
appropriate power supply units to these two headers to provide adequate power to your
system.
Backplane Power Connectors & GPU Power Connectors
In addition to the two SMCI-proprietary main power supply units located at PSU1/PSU2, 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.
Warning:
To provide adequate power to your system and to avoid damaging the power sup-
ply or the motherboard, be sure to connect all power connectors mentioned above to the
power supply. Failure in doing so may void the manufacturer warranty on your power supply
and motherboard.
