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.

8 Power Phase Design

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.

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.

2oz Copper PCB

2 ounce copper inner layers that provide stable signal traces and power shapes! Delivering lower temperature and higher energy efficiency for overclocking, it’s able to support the latest DDR4 memory modules with most extreme memory performance!

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.

Dual M.2 For SSD, Supports Type 22110 M.2

Ready for higher capacity and even faster Type 22110 M.2 NVMe SSD to fulfill the need of performance. Hyper M.2 socket that supports PCIe Gen4 x4 while M.2 socket is capable of running PCIe Gen3 x2 and SATA3 mode.

M.2 Armors

Good M.2 SSD protection is important for longevity and stability. ASRock provides a completed M.2 armor solution that makes SSDs to run in a certain low temperature.

AMD SMART ACCESS MEMORY

Conventional PC systems processor can only access a fraction of graphics memory and limits system performance. With AMD Smart Access Memory, the data channel gets expanded to harness the full potential of GPU memory, removes the bottleneck and increase performance.

Dual USB 3.2 Gen2 (Type-A + Type-C)

This motherboard has a pair of onboard Type-A and Type-C USB 3.2 Gen2 ports built on the rear i/o for supporting next generation USB 3.2 Gen2 devices and to deliver up to 10 Gbps data transfer rates.

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.

Post Status Checker

An easy troubleshooting tool that shows the CPU / DRAM / VGA / BOOT operation every time you start up the system. Post Status Checker is an fast and easy way to identify the source of the problem.

AMD StoreMI Technology

A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive, AMD StoreMI technology “combines” these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds.

3 Graphics Outputs

Complete with all three types of most used connectors! Packed with a D-Sub + DisplayPort + HDMI combo. Plus the HDMI port supports 4K resolution.
*Supported only with processors with integrated graphics. Please check CPU support list from each motherboard webpage.Full Spike Protection

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.
