aminimumpowerof350W.ThisPSUtypehas24-pinand4-pinpowerplugs.
• DONOTforgettoconnectthe4-pinATX+12Vpowerplug.Otherwise,thesystem
willnotbootup.
• WerecommendthatyouuseaPSUwithhigherpoweroutputwhenconguringa
systemwithmorepower-consumingdevicesorwhenyouintendtoinstalladditional
devices.Thesystemmaybecomeunstableormaynotbootupifthepoweris
inadequate.
