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_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).
USB 3.1 Gen 1 connector (20-1 pin U31G1_12) Connect a USB 3.1 Gen 1 module to this connector for additional USB 3.1 Gen 1 front or rear panel ports. This connector complies with USB 3.1 Gen 1 specifications and provide faster data transfer speeds of up to 5 Gbps, faster charging time for USB-chargeable devices, optimized power efficiency, and backward compatibility with USB 2.0.
Front panel audio connector (10-1 pin AAFP) This connector is for a chassis-mounted front panel audio I/O module that supports either HD Audio or legacy AC`97 audio standard. Connect one end of the front panel audio I/O module cable to this connector. • We recommend that you connect a high-definition front panel audio module to this connector to avail of the motherboard’s high-definition audio capability.
