ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to fit these connectors in only one orientation. Find the proper orientation and
push down firmly until the connectors completely fit.
•
We recommend that you use an EATX 12V Specification
2.0-compliant power supply unit (PSU) with a minimum of
300W power rating. This PSU type has 24-pin and 8-pin power
plugs.
•
DO NOT forget to connect the 4-pin ATX +12V power plug.
Otherwise, the system will not boot up.
•
We recommend that you use a PSU with higher power output
when configuring a system with more power-consuming
devices or when you intend to install additional devices. The
system may become unstable or may not boot up if the power
is inadequate.
•
If you are uncertain about the minimum power supply
requirement for your system, refer to the Recommended
Power Supply Wattage Calculator at http://support.asus.com/
PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us
for details.
