1-17Chapter 1: Product introduction
• 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 ATX +12V power plug. Otherwise, the system will
not boot up.
• We recommend that you use a PSU with higher power output 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.
2. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
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.
