The premium alloy chokes effectively increase up to 90% saturation current & feature a highly magnetic & heat resistant design, making the motherboard more efficient, stable & reliable. The Nex FET MOSFETs control the power supply to DRAM slots more efficiently. They provide lower RDS (on) 2.9 m O, delivering higher efficiency & lower temperature. ASRock does not overlook any details, even those tiny ones. With pure black PCB appearance, the Sapphire Black PCB represents rock-solid quality & gives the motherboard a more mysterious touch. Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream & entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3u A. This is the key to reduce noise level significantly & satisfy even the pickiest audiophiles. Intel LAN provides the best throughput performance, lower CPU utilization, enhanced stability & is able to deliver ultimate network experience to users! ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably & ensure longer lifetime. 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 & smoothly, so that the stability & lifespan of the motherboard is greatly enhanced. In a world where time is money, why waste precious time everyday typing usernames to log in? Why should even bother memorizing those foot long passwords? Nobody has time for that! Just plug in the USB (Universal Serial Bus) Key & let your computer log in automatically! Fast Boot is so fast that it is impossible for users to enter the UEFI setup utility during POST. Therefore, ASRock Restart to UEFI technology allows users to easily enter the UEFI setup utility automatically when turning on the PC next time. It is d
