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.

•You can connect the EZ Plug™ when using PCI Express graphics cards and a 20-pin ATX power supply unit; otherwise, the system will be unstable.

•Make sure that the PSU can support at least 8 A on the +12V_1 lead and 13 A on the +12V_2 lead.

•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.
