7.ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)

These connectors are for an ATX power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit.

•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.

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.
