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.
Tune it your way
Improved DDR4 stability
ASUS OptiMem 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
Cooler by design
Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
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.
USB 3.1 Gen 1 front-panel connector
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.
With x4 PCI Express® 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, providing fast access to data.
Intel Optane memory
Intel Optane™ is a revolutionary non-volatile memory technology supported by Prime 300 Series motherboards. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
Reliable stability and compatibility
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
Built to Last
ASUS is the world's leading motherboard brand. Our motherboards are extensively tested for compatibility with more than 1,000 components and devices, and each new model undergoes a minimum of 8,000 hours of strict validation — offering the peace of mind of knowing that your ASUS motherboard is fit for all environments and applications. Choosing ASUS is an assurance of trouble-free DIY experiences.
5X Protection III
Prime 300 Series motherboards are engineered with industry-leading 5X Protection III, employing the finest components, excellent circuit design and exacting standards to guarantee the quality and long-term durability of your investment. That means exceptional protection and stability for your build — thanks to decades of engineering experience from the world's leading motherboard brand.
1000+ Compatible devices and components
The superior compatibility of Prime 300 Series is evidenced by our extensive list of supported devices — which includes thousands of compatible components — and our Qualified Vendor List (QVL) that identifies memory compatibility. It all adds up to more choices for worry-free PC-building experiences.
8000+ VALIDATION HOURS
ASUS motherboards offer superb endurance. We verify this by subjecting every board to more than 8,000 hours of stringent tests. A barrage of burn-in, environmental, compatibility, software and safety tests confirm that our motherboards are exceptionally robust. It also shows that ASUS reliability surpasses industry standards, ensuring that every component is designed to function flawlessly in any environment.
Upgrade to unrivalled audio
Intelligent design and premium hardware create audio quality unlike anything you've ever experienced!
Visual beauty, virtual worlds
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura Sync offers full lighting connected via the motherboard's RGB header, with a variety of functional presets for external LED strips.* And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
* The Aura RGB-strip header supports 5050 RGB LED strips with a max power rating of 3A (12V). For maximum brightness, strip length should not exceed 3m.
LED strips and Aura Sync-compatible devices are sold separately.
Brighten Up Your Build
Built-in LED lighting options illuminate your build in a variety of eye-catching styles.
Beyond VR ready
Prime 300 series isn't just VR ready — it goes way beyond. The ASUS Beyond VR Ready marque means that Prime 300 series has been tested with loads of class-leading components to ensure that your productivity, gaming and entertainment needs are tuned for maximum performance. ASUS Beyond VR Ready opens up a new way to configure and build your dream system with total confidence.
