Important notes on motherboard power requirements
•
For a fully congured system, we recommend that you use a power
supply unit (PSU) that complies with ATX 12 V Specication 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.
•
Use of a PSU with a higher power output is recommended when
conguring 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.
