ASUS P5QL-EM 1-27
11. ATX power connectors (24-pin EATXPWR, 4-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to t these connectors in only one orientation. Find the proper orientation and
push down rmly until the connectors completely t.
• For a fully congured system, we recommend that you use a power supply unit (PSU)
that complies with ATX 12 V Specication 2.0 (or later version) and provides a minimum
power of 350 W.
• Do not forget to connect the 4-pin ATX12V power plug; otherwise, the system will not
boot.
• Use of a PSU with a higher power output is recommended when conguring a system
with more power-consuming 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.
• The ATX 12 V Specication 2.0-compliant (350W) PSU has been tested to support the
motherboard power requirements.
