4. ATX power connectors (20-pin ATXPWR1)
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.
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.
