7. ATX power connectors (24-pin ATXPWR, 4-pin ATX12V)
These connectors are for ATX 12V power supply. The plugs from
the power supply are designed to t these connectors in only one
orientation. Find the proper orientation and push down rmly until the
connectors completely t.
In addition to the 24-pin ATX power connector, this motherboard
requires that you connect the 4-pin ATX +12V power plug to provide
sufcient power to the CPU.
• 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 300W, or 350W for a fully
congured system. The system may become unstable or might not
boot up, if the power is inadequate.
