All-round energy efficiency
With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

Flexible cooling controls
Prime 300 Series motherboards offer comprehensive control over system fans, via the included Fan Xpert 2 software. Auto-Tuning mode intelligently configures all parameters with a single click.

Media-acclaimed UEFI BIOS
The UEFI BIOS is an early waypoint on any PC-building journey, and Prime 300 Series has one of the best in the business.

Ultrafast connectivity
USB 3.1 Gen 1 is right where you need it, with two super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.

Speed up with onboard M.2
With x4 PCI Express® 2.0 bandwidth, M.2 supports up to 20Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, providing fast access to data.
