ASUS P4SE/U2 Motherboard 1-13
3. ATX power connectors (4-pin ATX12V1, 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).
