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. 2-40 Chapter 2: Hardware information
