Asus P5K/EPU manual Front panel audio connector 10-1 pin Aafp

• 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 400 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 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 want to use two high-end PCI Express x16 cards, use a PSU with 500W to 600W power or above to ensure the system stability.

•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 Specification 2.0-compliant (400W) PSU has been tested to support the motherboard power requirements with the following configuration:

CPU: Intel® Pentium® Extreme 3.73GHz

Memory: 512 MB DDR3 (x4)

Graphics card: ASUS EAX1900XT
