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 4-pin EATX12 V power plug; otherwise, the

system will not boot up.

• To support an Intel

Dual-Core CPU up to 965 Extreme Edition, make sure

that the PSU can provide at least DC 16A (peak 22A) on the +12V_2 lead.
