3. 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.
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 300W or 350W for a fully
configured system. The system may become unstable and may
experience difficulty powering up if the power supply is inadequate.
