9. ATX power connectors (20-pin ATXPWR, 4-pin ATX12V)
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.
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.
1. Do not forget to connect the 4-pin ATX +12V power plug.
Otherwise, the system does not boot up.
2. 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.
