Whether you are using headphones, a headset, external or internal speakers, via USB, Wi-Fi, analog output or even HDMI, Nahimic Audio offers you the most engaging listening experience, vibrant and rich with details.
The Sound Tracker is a visual indicator that points out the directions from which predominant sounds are coming. Each sound is properly positioned in 360° on a radar for a full immersion during the game.
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.
Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.
Reduces 23% power loss and decreases the connector's temperature by 22 degrees Celsius.

This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear i/o for supporting next generation USB 3.1 Gen2 devices and to deliver up to 10 Gbps data transfer rates.
Front USB 3.2 Gen1 Type-C header delivers up to 5 Gbps data transfer rate and next generation reversible USB design to the front panel of computer case.
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.
Unlike most so called pre-mounted I/O shield that is only decorated with fancy color schemes. We reserve more tolerance space and allow IO shield is adjustable when installing, thus fitting chassis perfectly without any mechanical issue.
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.
Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Intelligently delivering higher current and driving up to 50A continuous current for each phase, thus providing improved thermal result and superior performance.
Specifically designed for memory power delivery, these new alloy chokes feature a highly magnetic and heat resistant design, thus delivering more stable and reliable power to the motherboard and memory modules.
Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20% longer lifespans and provide more stability and reliability.
A new designed protective cover for all of the crucial parts near the motherboard's rear I/O, so that they won't easily be damaged by static electricity.
A new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end motherboards.
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
Everything will wear off in time, but gold looks better! Gold audio jack provides stable sound transmission!
ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.
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.
