2.7.2 Internal connectors
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.
1. Internal power connectors (24-pin EATX_PWR1, 4-pin EATX_PWR3)
These connectors are for EATX power supply plugs. The power supply plugs
are designed to fit these connector in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit.

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!
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.
