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

Ultra M.2 32 Gb/s (PCIe Gen3 x4)
The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gb/s, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSDs.

Dual Band 802.11ac WiFi
No one has time for weak WiFi signals and sluggish internet! That’s why this motherboard comes with a 802.11ac WiFi (2.4G / 5G WiFi) module which supports wireless networks and Bluetooth v4.2.

4 x USB3.2 Gen1
Delivering data transfer rates up to 10X faster than USB 2.0 with optimized power efficiency. USB 3.2 Gen1 technology advances the data transfer rate up to 5Gb/s. ASRock provides 4 x USB 3.2 Gen1 ports onboard allows you to have a stunning data transfer experience.

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.

HDMI 4k @60Hz
Supports the most recent HDMI 4K 60Hz graphics output specification. With the larger bandwidth and increased frame rate, the motion on your screen becomes more fluid and less blurry.

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

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.
