This motherboard is specifically designed for mining the revolutionary digital crypto-currency that may be used anywhere in the world. The abundant onboard PCIe slots guarantee fast Crypto mining while the additional power connectors provide advanced system stability while mining.   Supports 7th and 6th Generation Intel Core™ i5/i3/Pentium® /Celeron® Processors Supports DDR4 2400/2133 MHz 1 PCIe 3.0 x16 12 PCIe 3.0 x1 Graphics Output: HDMI 7.1 CH HD Audio (Realtek ALC897 Audio Codec) 4 SATA3 1 M.2 (SATA3) 4 USB 3.2 Gen1 (2 Front 2 Rear) Intel® Gigabit LAN Onboard Power On / Reset Button M.2 For SSD M.2 socket supports 2260/2280/22110 SATA3 mode M.2 SSD for up to 6Gb/s. Smart PCIe State Detection This motherboard has included a smart way to show the status of every graphics card. While the system is booting the Power-On Self-Test (POST) screen will show the status of the graphics cards that were installed on the motherboard. Intel® LAN Intel® LAN provides the best throughput performance lower CPU utilization enhanced stability and is able to deliver ultimate network experience to users! Sapphire Black PCB Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch. High Density Glass Fabric PCB High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity. Power On / Reset Button Power On & Off system with onboard button is a must for open frame mining.   Digi Power Unlike traditional motherboards that use analog power this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design which provides CPU Vcore voltage more efficiently and smoothly so that the stability and lifespan of the motherboard is greatly enhanced.   Full Spike Protection Some sensitive digital components on the motherboard are vulnerable to power surges the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard’s components from being damaged by these unexpected voltage spikes.
