M.2 with PCIe-Gen2-x4 The PCIe-Gen2-x4 interface drives the data transfer rate up to 20Gb / s. In addition, it offers support for M.2 modules with SATA3 (6Gb / s) and is compatible with the U.2 kit from ASRock, which enables the installation of U.2 SSDs. Intel® LAN Intel® LAN offers the best data throughput, low CPU utilization and improved stability. It gives users the ultimate network experience! Sapphire Black PCB A pure black PCB. The new sapphire black PCB represents the high quality and gives the mainboards a mysterious touch. High density fiberglass PCB The high-density fiberglass PCB reduces the gaps between the PCB layers to protect the mainboard from short circuits caused by moisture. 4K x 2K Has at least 3840 x 2160 pixels, which is twice the horizontal and vertical resolution of the 1080p format. 3 graphics outputs complete with the three most popular connection types! Equipped with D-Sub + DVI + HDMI. The HDMI port also supports full HD playback (1080p) from Blurays. Audio capacitors from ELNA Who said that high-quality sound is only possible with high-end motherboards? ASRock installs audio capacitors from ELNA on mainstream and entry-level mainboards! Compared to conventional solid capacitors, the leakage current is only a marginal 3 uA. This is the key to significantly lowering the noise level and satisfying even the most discerning audiophile. A-Tuning A-Tuning is ASRock's multi-purpose software with a new interface, more features and improved tools! Full spike protection Some sensitive digital components of the mainboard are susceptible to current fluctuations, so that excessive voltages can lead to malfunctions in the system. ASRock's so-called "Full Spike Protection" combines various technologies that can prevent damage to mainboard components from unexpected voltage fluctuations.
