4. ATX power connectors (20-pin ATXPWR, 4-pin ATX +12V)
These connectors are for an ATX 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.
• Do not forget to connect the 4-pin ATX +12V power plug; otherwise,
the system does not boot up.
• 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 250W, or 300W for a fully
configured system. The system may become unstable or may not
boot up if the power is inadequate.
