8. ATX power connectors (24-pin EATXPWR, 2x4-pin EATX12V)

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

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

orientation and push down firmly until the connectors completely fit.

• Make sure to remove the cap on the EATX12V connector before connecting

an 8-pin EPS +12V power plug.

• Use only either a 4-pin ATX12V or an 8-pin EPS +12V power plug for the

EATX12V connector.

• For a fully configured system, we recommend that you use a power supply

unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)

and provides a minimum power of 400 W.

• Do not forget to connect the 8-pin / 4-pin EATX12V power plug; otherwise,

the system will not boot.

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

configuring 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 two high-end PCI Express x16 cards, use a PSU with

500W to 600W power or above to ensure the system stability.

• If you are uncertain about the minimum power supply requirement for your

system, refer to the Recommended Power Supply Wattage Calculator

at http://support.asus.com/PowerSupplyCalculator/PSCalculator.
