ASUS Prime 300 Series motherboards provide the solid foundation needed for your first build, plus flexibility to grow with your ambitions. We've melded all the good stuff that's packed into the latest 8th Generation Intel® Core™ processors with essential ASUS design and engineering, so you benefit from industry-leading technologies - including automated system tuning, comprehensive cooling controls, and immersive onboard audio. When you build with an ASUS Prime 300 Series motherboard, you build smart, easy and affordable.

OptiMem: Improve DDR4 Stability
ASUS OptiMem peserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements allow the Prime 300 Series to support a wide range of dual and quad-DIMM memory kits, while providing your rig with the stability it needs to deal with any type of workload - whether you're gaming or running intensive application

ASUS OptiMem benefits:
- Improved memory stability and compatibility
- Allows lower memory latencies at equivalent voltages
- Improved memory frequency margin
Tested by using Synopsys HSPICE simulation software

A larger signal eye results in improved stability, more overclocking headroom, and lower operating voltages

EPU:All-round energy efficiency

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 Expert 2+ software. Auto-Tuning mode intelligently configures all parameters with a single click.

Tune it Your WayCooler by Design

Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.

Multiple temperature sources
Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.

4-pin PWM/DC fan
Each onboard CHA FAN header supports PWM and DC mode

UEFI

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

Q-Fan Control
Can configure the fan's operating speed manually, or use the easy pre-configured fan profiles to select Standard, Silent, Turbo or Full Speed modes, plus automatic switch to full speed if the temperature hits 75°C.

Search Function
When you're ready for a deeper dive, Advanced mode enables full control over every aspect of the motherboard - with a built-in Search function to find the setting you need in the blink of an eye.

EZ mode

EZ Tuning Wizard
