11.ATX power connectors

(24-pin EATXPWR; 8-pin EATX12V1, 8-pin EATX12V, 8-pin EATX12V1, 6-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.

•

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 350 W.

 

 

•

DO NOT forget to connect the 4-pin/8-pin EATX12 V power plug. Otherwise, the

 

 

 

system will not boot.

 

 

•

We recommend that you use a PSU with a 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.

 

 

•

If you want to use two or more high-end PCI Express x16 cards, use a PSU with

 

 

 

1000W 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.
