8. ASUS EZ Plug™ and ATX power connectors
(20-pin ATXPWR1, 4-pin EZ_PLUG1, 4-pin ATX12V1)
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 ATXPWR1 connector, this motherboard
requires that you connect the 4-pin ATX +12V power plug to provide
sufficient power to the CPU.
If you are using a standard ATX power supply that does not have the
ATX +12V plug, connect one 4-pin device power plug to the ASUS EZ
Plug™ connector labeled EZ_PLUG1.
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 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.
