•

For a fully conﬁgured system, we recommend that you use a power supply

unit (PSU) that complies with ATX 12V Speciﬁcation 2.0 (or later version)

and provides a minimum power of 550 W.

•

Do not forget to connect the 4-pin/8pin EATX12V 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 high-end PCI Express x16 cards, use a PSU with

500 W to 600 W power or above to ensure the system stability.
