• 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.
• The ATX 12 V Specication 2.0-compliant (400W) PSU has been tested to support the
motherboard power requirements with the following conguration:
