Internal connectors
1.
Internal power connectors (8-pin EATX_PWR2)
This connector is for an EATX power supply plug. The power supply plug
is designed to fit this connector in only one orientation. Find the proper
orientation and push down firmly until the connector completely fits.
IMPORTANT:
•
For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12V Specification 2.0 (or later version).
•
We recommend that you use a PSU with higher power output when
configuring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
For safety purpose, use ONLY the bundled power adapter to avoid damaging
your motherboard.
2.
Chassis / CPU Fan headers (4-pin CHA_FAN1, 4-pin CPU_FAN1)
Connect the fan cables to the fan headers on the motherboard, ensuring that
the black wire of each cable matches the ground pin of the header.
CAUTION: Do not forget to connect the fan cables to the fan connectors.
Insufficient air flow inside the system may damage the motherboard
components. These are not jumpers! Do not place jumper caps on the fan
connectors!
