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 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 affordably.
AsusOptiMem preserves 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 applications
A larger signal eye results in improved stability, more overclocking headroom, and lower operating voltages
Tested by using Synopsys HSPICE simulation software
EPU
Fan Xpert 2+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.
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.
Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
Multiple temperature sources
4-pin PWM/DC fanEach header can monitor and react to dedicated thermal sensors.
