• 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 400 W.

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.
