• For a fully congured system, we recommend that you use a power supply unit (PSU)
that complies with EATX 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 ATX12V power plug. Otherwise, the system will not
boot.
• We recommended that you use a PSU with a higher power output 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.
