10. ASUS EZ Plug™ and ATX power connectors

(20-pin ATXPWR, 4-pin ATX+12V, 4-pin AUX+12V)

These connectors connect to an ATX 12V power supply. The plugs

from the power supply are designed to fit these connectors in only one

orientation. Find the proper orientation and push down firmly until the

connectors completely fit.

In addition to the 20-pin ATXPWR connector, this motherboard

requires that you connect the 4-pin ATX +12V power plug to provide

sufficient power to the CPU.

If you are using a standard ATX power supply that does not have the

added ATX +12V plug, then simply connect one of the 4-pin device

power plugs into the ASUS EZ Plug™ connector labeled AUX12V.

Make sure that your ATX 12V power supply can provide 8A on the

+12V lead and at least 1A on the +5V standby lead (+5VSB). The

minimum recommended wattage is 230W, or 300W for a fully

configured system. The system may become unstable and may

experience difficulty powering up if the power supply is inadequate.
