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 Chapter 3 before installing or removing components.
4.1 Power Connections
Two power connections supply the motherboard and several more supply for onboard devices.
Main Power Connector
Two proprietary main power headers are located at PSU1 and PSU2. Connect appropriate
power supply units to these two headers to provide adequate power to your system.
Important:
To provide adequate power to the motherboard, connect the both main power
connectors to the power supply. Failure to do so may void the manufacturer's warranty on
your power supply and motherboard.
GPU Power Connectors
Graphic processor units (GPUs) and video devices are powered by 8-pin connectors, JGPW2/
JGPW4. Connect appropriate cables.
