¥You may use a 4-pin ATX12V power plug for this connector.

¥Make sure to remove the cap on the connector before connecting an 8-pin EPS +12V power plug.

¥Use only either a 4-pin ATX12V or an 8-pin EPS +12V power plug. Connecting other power plug types may cause serious damage to the system.

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

: Intel¨ Pentium¨ 4 3.73 GHz Extreme Edition

Memory

: 512 MB DDR2 (x 4)

Graphics card

: PCI Express x16 Nvidia 6600GT

Parallel ATA device

: IDE hard disk drive

Serial ATA device

: SATA hard disk drive (x2)

Optical drives

: 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. The vendors list on the next page is provided for your reference.
