5. ATX power connectors (20-pin ATXPWR1) 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. Make sure that your ATX 12V power supply can provide 8A on the +12V lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum recommended wattage is 250W, or 300W for a fully configured system. The system may become unstable and may experience difficulty powering up if the power supply is inadequate. ® P4VP-MX P4VP-MX ATX Power Connector ATXPWR1 +12.0VDC +5VSB PWR_OK COM +5.0VDC COM +5.0VDC COM +3.3VDC +3.3VDC +5.0VDC +5.0VDC -5.0VDC COM COM COM PS_ON# COM -12.0VDC +3.3VDC 6. CPU and chassis fan connectors (3-pin CPU_FAN1, CHA_FAN1) The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Lack of sufficient air flow within the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors! ® P4VP-MX Rotation +12V GND CPU_FAN1 CHA_FAN1 Rotation +12V GND P4VP-MX 12-Volt Cooling Fan Power ASUS P4VP-MX motherboard 1-19
