3. ATX power connectors (20-pin ATXPWR)

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 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.

4. 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.
