Speed Up with Onboard M.2 Up to 32Gb/s

With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gb/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible.

Advanced fan controls

ASUS Prime 200 series motherboards feature best-ever cooling capability, controllable from Fan Xpert 4 Core and from the UEFI. Two modes are available firstly, Auto-Tuning Mode which scans fan parameters and all fans with a single click, and Extreme Quite Mode that reduces the CPU fan speed to below the default minimum, for extra-quiet operation and power savings during light loads.
