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 connector supports the provided floppy drive ribbon cable. After

connecting one end to the motherboard, connect the other end to the floppy

drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon

cables with pin 5 plug).

NOTE: Orient the red markings o

the floppy ribbon cable to PIN 1.
