ASUS P8H61-M PLUS V2 1-18
• 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 350 W.
• 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 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 are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
