Asus P5WD2 Motherboard Installation Guide - Page 61

Important notes on motherboard power requirements • 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 8-pin/4-pin EATX12 V power plug; otherwise, the system will not boot up. • Make sure that the PSU can support at least 8 A on the +12V_1 lead and 13 A on the +12V_2 lead. • The ATX 12 V Specification 2.0-compliant (400 W) PSU has been tested to support the motherboard power requirements with the following configuration: CPU : Memory : Graphics card : Parallel ATA device : Serial ATA device : Optical drives : Intel® Pentium® 4 3.73 GHz Extreme Edition 512 MB DDR2 (x 4) PCI Express x16 Nvidia 6600GT IDE hard disk drive SATA hard disk drive (x2) DVD-RW • 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 graphics cards, use a PSU with 450 to 500 W power to ensure system stability. • To support an Intel® Dual-Core CPU up to 840 Extreme Edition, make sure that the PSU can provide at least DC 16A (peak 22A) on the +12V_2 lead.
