ASUS P4P800-X motherboard 1-21
4. ATX power connectors (20-pin ATXPWR, 4-pin ATX12V)
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 ATX power connector, this motherboard requires that
you connect the 4-pin ATX +12V power plug to provide sufficient power to the
CPU.
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 for a fully configured system. The system may
become unstable and may experience difficulty powering up if the power supply
is inadequate.
5. Internal audio connectors (4-pin CD, AUX)
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM, TV tuner, or MPEG card.
