2-34 Chapter 2: Hardware information
Chapter 2
• 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 450 W.
• Do not forget to connect the 4-pin/8-pin EATX12 V power plug; otherwise, the system
will not boot.
• 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 or more high-end PCI Express x16 cards, use a PSU with
1000W power or above to ensure the system stability.
• If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at
