• Use of an SSI 12 V Specication 2.0-compliant power supply unit
(PSU) that provides a minimum power of 450 W is recommended for
a fully-congured system.

incorrent insertion of a 4-pin ATX +12V power plug. Remove this
cover when using a PSU with an 8-pin ATX +12V power plug.
• Do not forget to connect the 4-pin or 8-pin ATX +12 V power plug;
otherwise, the system will not boot up.

conguring a system with more power consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
• You must install a PSU with a higher power rating if you intend to
install additional devices.
