• For a fully-configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specification 2.� (or later version)
and provides a minimum power of 400 W.
• Do not forget to connect the 4-pin ATX �12 V power plug; otherwise, the
system will not boot up.
• 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.
• If you want to use the ATI CrossFire ™ Graphics solution, use a PSU with
500 ~ 600 W power to ensure system stability.
