10.ATX power connectors (20-pin ATXPWR, 4-pin ATX12V)

These connectors are for the power plugs from the ATX power supply unit. The plugs are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit.

In addition to the 20-pin ATXPWR connector, this motherboard requires that you connect the 4-pin ATX +12V power plug to provide sufficient power to the CPU.

• Do not forget to connect the 4-pin ATX +12V power plug. Otherwise, the system does not boot up.

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 or may not boot up if the power is inadequate.
