Nahimic Audio

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.


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

ASRock motherboards deliver stunning performance and superior aesthetics to rule your own colorful lighting way! ASRock offers a very comprehensive control to perform the built-in RGB LEDs or the connected LED strips, CPU fans, coolers, chassis and any RGB devices smoothly. Devices can be synchronized across the Polychrome RGB Sync-certified accessories as well.


*The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.

*The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters.


A SOLID M.2-SOLUTION PERFORMER

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.


Reinforced Steel Slot [PCIe 4.0 Version]

The reinforced steel slot comes with the next generation PCI Express 4.0 standard. The various benefits include:

  • Extra anchor points
  • Stronger latch
  • Ensure signal stability
  • Make sure heavy graphics cards to be well-installed.


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.

  • USB 3.2 Gen2 doubles the data transfer rate
  • USB 3.2 Gen2 Type-C doubles the charge speed!


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.

*Wi-Fi module is not included.


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.


XXL Aluminum Alloy Heatsink

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.


Sapphire Black PCB

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


High Density Glass Fabric PCB

High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.


2oz Copper PCB

Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
