ASUS K8V-VM Motherboard 1-23
5. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The plugs from the power
supply are designed to t these connectors in only one orientation. Find the
proper orientation and push down rmly until the connectors t completely.
• Do not forget to connect the 4-pin ATX +12V power plug; otherwise, the
system does not boot up.
• Make sure that your ATX 12V power supply can provide 12A on the +12V
lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum
recommended wattage is 300 W, or 350 W for a fully congured system.
The system can become unstable or will not boot up if the power is
inadequate.
