H87I-PLUS ATX power connectors

•We recommend that you use an ATX 12V Specification 2.0‑compliant power supply

unit (PSU) with a minimum of 300W power rating. 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 configuring 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.

•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.
