ATX power connectors (24-pin EATXPWR, 8-pin EATX12V) These connectors are for ATX power supply plugs. The power supply plugs are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. • We recommend that you use an ATX 12V Specification 2.0‑compliant power supply unit (PSU) with a minimum of 350W power rating. This PSU type has 24-pin and 8-pin power plugs. • DO NOT forget to connect the 8-pin EATX +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.cn/PowerSupply.aspx?SLanguage=en for details. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1/2) Connect the fan cables to the fan connectors on the motherboard, ensuring that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! Do not place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan of maximum 1A (12 W) fan power. M.2 socket 3 This socket allows you to install M.2 (NGFF) SSD modules. M.2(SOCKET3) 22110 2280 2260 2242 • The M.2 socket supports PCIe 3.0 x4 mode and SATA mode M Key design and type 2242 / 2260 / 2280 / 22110 storage devices. • The M.2 Socket shares bandwidth with the SATA_5/6 ports, and therefore the SATA_5/6 ports cannot be used when an M.2 device is installed. AMD AM4 CPU socket The motherboard comes with an AMD AM4 socket designed for AMD Ryzen™ 2nd Generation/ Ryzen™ with Radeon™ Vega Graphics/ Ryzen™ 1st Generation processors.
