ASUS A8V 2-25
6. ATX power connectors (20-pin ATXPWR, 4-pin ATX12V)
These connectors are for 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 ATX power connector, this motherboard
requires that you connect the 4-pin ATX +12V power plug to provide
sufficient power to the CPU.
• 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 8A on the
+12V lead and at least 1A on the +5-volt standby lead (+5VSB).
The minimum recommended wattage is 300W, or 350W for a fully
configured system. The system may become unstable or might not
boot up, if the power is inadequate.
