4-10 Chapter 4: Motherboard info

•

For a fully congured system, we recommend that you use a power supply

unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)

and provides a minimum power of 400 W.

• Do not forget to connect the 4-pin EATX12V power plug; otherwise, the

system will not boot.

• Use of a PSU with a higher power output is recommended when

conguring a system with more power-consuming devices. The system

may become unstable or may not boot up if the power is inadequate.

• If you want to use PCI Express x16 card, use a PSU with 500W to 600W

power or above to ensure the system stability.

11. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)

These connectors are for ATX power supply plugs. The power supply plugs

are designed to t these connectors in only one orientation. Find the proper

orientation and push down rmly until the connectors completely t.
