Ready for higher capacities and even faster Type 22110 M.2 NVMe SSDs to fulfill the need for high performance.

Intel® LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users!

The advanced PCI-E steel slots packed with solid cover prevent any signal interference with graphics cards. They also ensure heavy graphics cards can be well-installed in the PCI-E slots safely.

Supports Intel® Optane™ memory technology and Intel® Optane™ storage technology that redefines a new standard of high performance and responsiveness.


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.

Designed with a 10 Power Phase Design, this motherboard provides completely smooth power delivery to the CPU and offers unmatched overclocking capabilities and enhanced performance with the lowest temperature.

Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.

The high-density glass-fabric PCB design reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

This is not only a standard CPU fan header, but also supports water pumps! This header provides a maximum of 2A power for supporting the most popular water pumps. User also can adjust the voltage of water pump to get higher cooling performance with lower noise.

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.

ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably and ensure longer lifetime.

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.

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.
