1. 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 ATX 12V Specification 2.0-compliant power supply unit
(PSU) with a 450W or lower power rating. This PSU type has 24-pin and 4-pin power
plugs.
• If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin
power plug can provide at least 15 A on +12 V and that the PSU has a power rating of
450W or lower. The system may become unstable or may not boot up if the power is
inadequate.
• DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will
not boot up.
• 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.
