13. ATX power connectors and ASUS EZ Plug™ (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 at least 8A on the +12V lead and at least 1A on the +5-volt 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. +5.0VDC +5.0VDC -5.0VDC COM COM COM PS_ON# COM -12.0VDC +3.3VDC AUX12V ATXPWR Pin 1 +12V GND GND +5V +12.0VDC +5VSB PWR_OK COM +5.0VDC COM +5.0VDC COM +3.3VDC +3.3VDC P4S8X +12V DC ® ATX12V P4S8X ATX & Auxiliary Power Connectors +12V DC COM Pin 1 COM ASUS P4S8X motherboard user guide 33
