Digi Power

Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.


High Speed M.2 Solution

This motherboard is capable of accomadating multiple M.2 storage devices, one of which can support PCI Express 4.0 M.2 SSD, it is capable of performing twice the speed compared to previous 3rd generation, giving a lightning fast data transferring experience.


Intel® Gigabit LAN

Intel® LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users!
