2-28 Chapter 2: Hardware information
•
For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specication 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
conguring 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 Specication 2.0-compliant (400W) PSU has been tested
to support the motherboard power requirements with the following
conguration:
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.
