F2A55-M ATX power connectors

•For a fully configured system, we recommend that you use a power supply unit

(PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum power of 300 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 configuring 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.
