•You can also use a Power Supply Unit (PSU) with a 24-pin ATX power

connector on this motherboard.

•Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will not boot up.

•Use a PSU with a minimum power rating of 300 W on this motherboard. We recommend that you use a PSU with a 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.
