3.ATX power connector (24/20-pin EATXPWR)

This connector is for a 24/20-pin power plug from an ATX 12V power supply. The plug from the power supply is designed to fit this connector in only one orientation. Find the proper orientation and push down firmly until the plug completely fits.

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.
