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. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
• Unplug the power cord before installing or removing the motherboard. Failure to do so
can cause you physical injury and damage to motherboard components.

CPU and chassis fan connectors; AIO pump connector (4-pin CPU_FAN,
4-pin CHA_FAN1/2/3; 4-pin AIO_PUMP)
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. Insufcient air ow 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.
AMD AM4 CPU socket
This motherboard comes with an AMD AM4 socket designed for AMD Ryzen™
2nd Generation / Ryzen™ with Radeon™ Vega Graphics / Ryzen™ 1st Generation
processors.
For more details, refer to Central Processing Unit (CPU).
Aura RGB Strip header (4-pin RGB_HEADER)
This header is for RGB LED strip.
ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to t these connectors in only one orientation. Find the proper orientation
and push down rmly until the connectors completely t.
• For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX12V Specication 2.0 (or later version) and provides a
minimum power of 350 W. 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 conguring 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.
The RGB header supports 5050 RGB
multi-color LED strips (12V/G/R/B), with a
maximum power rating of 3A (12V), and
no longer than 3m.

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. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.
• Actual lighting and color will vary with LED strip.
• If your LED strip does not light up, check if the RGB LED extension cable and the
RGB LED strip is connected in the correct orientation, and the 12V connector is
aligned with the 12V header on the motherboard.
• The LED strip will only light up when the system is operating.
• The LED strips are purchased separately.
DDR4 DIMM slots
Install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered DDR4 DIMMs into these DIMM sockets.

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 Serial ATA 6.0Gb/s connectors (7-pin SATA6G_1~6)
These connectors connect to Serial ATA 6.0 Gb/s hard disk drives via Serial ATA
6.0 Gb/s signal cables.
System panel connector (20-5 pin F_PANEL)

Gen 1 front or rear panel ports. This connector complies with USB 3.1 Gen 1
specications and provides faster data transfer speeds of up to 5 Gbps, faster
charging time for USB-chargeable devices, optimized power efciency, and
backward compatibility with USB 2.0.
USB 2.0 connectors (10-1 pin USB34,USB56)
Connect a 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 2.0 specications and support up to 480Mbps connection speed.

This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR4 DIMM sockets:
• You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.

Channel A DIMM_A1 & DIMM_A2*
Channel B DIMM_B1 & DIMM_B2*
• For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs).
• Refer to www.asus.com for the latest Memory QVL (Qualied Vendors List)
