1 Product introduction Motherboard overview • Unplug the power cord from the wall socket before touching any component. • Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity. • Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply.
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. • 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 300 W. This PSU type has 24-pin and 4-pin power plugs.
DDR4 DIMM slots Install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered non-ECC DDR4 DIMMs into these DIMM sockets. For more details, refer to System memory. Clear RTC RAM (2-pin CLRTC) CLRTC +3V_BAT GND This header allows you to clear the CMOS RTC RAM data of the system setup information such as date, time, and system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Use a metal object such as a screwdriver to short the two pins. 3.
PCI Express 3.0 / 2.0 x16 slot This motherboard supports one PCI Express 3.0 / 2.0 x16 graphic card that complies with the PCI Express specifications. RTC Battery header (2-pin BATT_CON) This connector is for the lithium CMOS battery. USB 2.0 connectors (10-1 pin USB34, USB56) These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a slot opening at the back of the system chassis. These USB connectors comply with USB 2.
