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.
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.
IR® Digital PWM
The onboard IR® Digital PWM controller delivers the most precise and stable power so that users may achieve optimal performance.
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.
Supports 4-Way SLI with NVIDIA® Quadro® & GTX VGA Cards
This flagship motherboard is able to support 4-Way SLI or 4-Way CrossFireX effortlessly. Not only support GeForce GTX multi-GPU, it is also fully compatible with NVIDIA® Quadro® professional desktop workstation graphics solutions 4-Way SLI.

*Please refer to NVIDIA® website for the 4-Way SLI supported graphics card list.
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.
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. * Teaming is not supported with Windows® 10.
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.>
*Performance result may vary with a different configuration.
