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.
