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 A before installing or removing components.
4.1 Power Connections
Three power connections on the X11DPD-M25 must be connected to the power supply.
•
14-pin Primary ATX Power (JPWR3)
•
8-pin Processor Power (JPWR1/JPWR2)
Primary ATX Power Connector
JPWR3 is the 14-pin ATX main power supply connector.
Important:
To provide adequate power to the motherboard, connect the 14-pin
and
the 8-pin
power connectors to the power supply. Failure to do so may void the manufacturer's warranty
on your power supply and motherboard.
12V 8-pin CPU Power Connectors
JPWR1 and JPWR2 are the 8-pin 12V DC power inputs for the CPU or alternative single
power source for a special enclosure when the 14-pin ATX power is not in use.
