1-14 Chapter 1: Motherboard Information
4. ATX power connectors (20-pin ATX_POWER1)
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.
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.
