• 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.

Do not forget to connect the 4-pin ATX12V 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.

The ATX 12 V Specification 2.0-compliant (400W) PSU has been tested to support the motherboard power requirements.
