6. ATX power connectors (24/20-pin EATXPWR, 8-pin CON12V)
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 24/20-pin EATXPWR connector, this motherboard
requires that you connect the 8-pin +12V power plug to the CON12V
connector to provide sufficient power to the CPU.
Make sure that your ATX 12V power supply can provide 20A on the
+12V lead and at least 1A on the +5-volt standby lead (+5VSB). The
minimum recommended wattage is 300W for a fully configured system.
The system may become unstable and may experience difficulty
powering up if the power supply is inadequate.
