Asrock 90-MXB7B0-A0UAYZ X399M Taichi Amd X399 Socket 90-MXB7B0-A0UAYZ

11 Power Phase Design
Designed with an 11-Power-Phase Design, this motherboard features 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.

IR� Digital PWM
The onboard IR� Digital PWM controller delivers the most precise and stable power so that users may achieve optimal performance.

8-Layer PCB / Better DDR4 Performance
The 8 Layer PCB comes with 4 sets of 2 ounce copper inner layers, providing stable signal traces and power shapes and delivering lower temperature and higher energy efficiency for overclocking! Thus, it's able to support the latest DDR4 memory modules with most extreme memory performance!

Dr. MOS
Dr. MOS is optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.

Separated CPU Power Connector Design
Unlike traditional dual CPU power connectors which are located closely together at the same side, ASRock separates them to either side of motherboard in order to create wider trace for CPU VRM. This design brings better power delivery efficiency and lower temperature, thus improving system stability and increasing overclocking potential.

Dual Intel� LAN
Users are able to connect two LAN cables to this motherboard's rear I/O. Dual LAN with Teaming function enabled on this motherboard allows two single connections to act as one single connection for twice the transmission bandwidth, making data transmission more effective.

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.

Triple Ultra M.2
Triple of the world�s fastest PCIe Gen3 x4 Ultra M.2 slots that deliver up to 32Gb/s transfer speed, it also supports SATA3 6Gb/s M.2 modules.

Supports Type 22110 M.2
Ready for higher capacity and even faster Type 22110 M.2 NVMe SSD to fulfill the need of performance

XL 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.

Premium 60A Power Choke
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.

Premium Memory Alloy Choke
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.

Dr. MOS
Dr. MOS design features the latest SPS (Smart Power Stage) technology. It�s optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.

Nichicon 12K Black Caps
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.

I/O Armor
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.

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

BIOS Flashback
Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and power supply, No CPU, RAM or other components required.

U.2 Connector
U.2 is for connecting some of the world�s fastest U.2 PCIe Gen3 x4 SSDs.

PCI-E STEEL SLOTS
The advanced PCI-E Steel Slots packed with solid cover that prevent any signal interference with graphics cards. It also ensures the heavy graphics cards to be well-installed in the PCI-E slots safely.

Purity Sound 4
It's time to enjoy the most purified audio performance with ultra high definition. Purity Sound4 is a combination of several hardware, software audio solutions. 7.1 CH HD audio with the latest Realtek ALC1220 audio codec, individual PCB layers for R/L audio channel, 120dB SNR DAC and other technologies to deliver the crispest sound effects.

Dual USB 3.1 Gen2 (Type-A + Type-C)
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.

RGB LED
Build your own colorful lighting system! RGB LED and header allows users to connect LED strip and create their unique PC style easily. The ASRock RGB LED utility can be downloaded directly or from an all-in-one utility ASRock Live Update & APP Shop!

A-Tuning
A-Tuning is ASRock's multi purpose software suite with a new interface, more new features and improved utilities.

Live Update & APP Shop
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.
