RULE YOUR OWN LIGHTING WAY - POLYCHROME RGB This motherboard features onboard RGB headers and an addressable RGB header that allow motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects. *The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters. *The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters. Dual M.2 For SSD Equipped with M.2 slot that supports both SATA3 6Gb/s and PCIe Gen3 x4 Ultra M.2 interface that pushes data transfer speeds up to 32Gb/s, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSD. Full Coverage M.2 Heatsink A massive full coverage M.2 heatsink that is able to dissipate heat efficiently to ensure your high speed M.2 SSD always working at its best. XXL Aluminum Alloy Heatsink Extra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable. PCI-E STEEL SLOT The advanced PCI-E Steel Slot packed with solid cover that prevent any signal interference with graphics cards. It also ensures the heavy graphics cards to be well-installed in the PCI-E slot safely. Intel® LAN Intel® LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users! Intel® Optane™ Memory Ready Supports Intel® Optane™ memory technology and Intel® Optane™ storage technology that redefines a new standard of high performance and responsiveness. ASRock Intel® 4-Layer Memory POOL Technology POOL (Planes On Outer Layers) technology allows 4-layer boards to utilize stripline routing instead of micro-strip routing, making motherboard having better electrical properties and performance. Super Alloy Motherboard Premium 50A Power Choke Compared to traditional chokes, ASRock’s premium 50A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard. 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. Digi Power This motherboard uses a next generation Hybrid Digi Power design to bring precise control and smooth power. With the ensured efficient and clean power delivery to the CPU, the stability and lifespan of motherboard is also greatly enhanced. M.2 (KEY E) For WiFi Besides the onboard LAN port, users may also choose 802.11ac wireless connections by M.2 (Key E) slot. *Wi-Fi module is not included. 3 Graphics Outputs Complete with all three types of most used connectors! Packed with a D-Sub DVI-D HDMI combo. Triple Monitor Graphics, graphics and even more graphics! Youve demanded for more eye candy, so this motherboard supports Triple Monitor. You may choose up to three display interfaces from the rear i/o to connect monitors and use them simultaneously without installing another graphics card. ELNA Audio Caps Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream and entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3uA. This is the key to reduce noise level significantly and satisfy even the pickiest audiophiles. A-Tuning A-Tuning is ASRocks multi purpose software suite with a new interface, more new features and improved utilities.
