Safety information
Electrical safety
•To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.
•When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.
•Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.
•Seek professional assistance before using an adapter or extension cord. These devices could interrupt the grounding circuit.
•Ensure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.
•If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer.
Operation safety
•Before installing the motherboard and adding components, carefully read all the manuals that came with the package.
•Before using the product, ensure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately.
•To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry.
•Avoid dust, humidity, and temperature extremes. Do not place the product in any area where it may be exposed to moisture.
•Place the product on a stable surface.
•If you encounter technical problems with the product, contact a qualified service technician or your retailer.

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.

ATX power connectors (24-pin EATXPWR_A/B/C, 8-pin EATX12V, 4-pin AUXPWR_A1/A2/A3)
Correctly orient the ATX power supply plugs into these connectors and push down firmly until the connectors completely fit.
•In order to fully support 19 graphic cards mining, we recommend that you use 3
power supply units (PSU) that are designed for mining with sufficient 12V power plugs and provide a minimum power of 3750W in total (2*1250W + 1*1350W are recommended).
•AUXPWR_A1/A2/A3 must be connected to the same power supply plugged in the 24-pin EATXPWR_A connector.
•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/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
Intel® LGA1151 CPU socket
Install Intel® LGA1151 CPU into this surface mount LGA1151 socket, which is designed for 7th/6th Generation Intel® Core™ i7 / i5 / i3, Pentium®, and Celeron® processors.
For more details, refer to Central Processing Unit (CPU).
CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN)
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.
DDR4 DIMM slots
Install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered non-ECC DDR4 DIMMs into these DIMM sockets.
• To make your build more stable, when using 8 or more cards for mining, we recommend that you install 4GB memory modules and change the size of the virtual memory paging file to 30GB.
•For more details, refer to System memory.
