ASUS P4SGL-MX Motherboard 1-15
4. ATX power connectors (20-pin ATXPWR1, 4-pin ATX12V1)
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.
5. USB headers (10-1 pin USB34, USB56)
USBPWR34 and USBPWR56 is for the internal USB header that you can
connect to the front USB ports.
The USB module is not included in the package.
