ASUS A7N8X Motherboard 1-13
3. 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.
If you will need to replace the power supply in the future, make sure
that your new 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.
2. Floppy disk drive connector (34-1 pin FLOPPY1)
This allows you to disable or enable the keyboard power up function. Retain
the default setting of [1-2] to disable computer keyboard-wake-up function. If
you set to [2-3] you may use your keyboard by pressing to wake
up your computer. This feature requires an ATX power supply that can supply
at least 1A on the +5VSB lead.
