• 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/8pin EATX12V 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.

•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 DDR2 (x4)

Graphics card: ASUS EAX1900XT

Parallel ATA device: IDE hard disk drive

Serial ATA device: SATA hard disk drive (x2)

Optical drive: DVD-RW

•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.
