•

For a fully congured system, we recommend that you use a power supply unit (PSU)

that complies with ATX 12 V Specication 2.0 (or later version) and provides a minimum

power of 400 W.

• Do not forget to connect the 4-pin EATX12V power plug; otherwise, the system will not

boot.

• Use of a PSU with a higher power output is recommended when conguring a system

with more power-consuming devices. The system may become unstable or may not boot

up if the power is inadequate.
