Careful routing of traces and vias to preserve signal integrity for improved memory stability.Flexible controls for ultimate cooling and quietness, plus GPU-temperature sensing for cooler gaming. Multiple hardware safeguards for all-round protection.Onboard connector for RGB LED strips, easily synced with an ever-growing portfolio of Aura Sync-capable hardware.Supreme flexibility with native M.2 support for Lightning-fast storage speeds.

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.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.

USB 3.1 Gen 1 front-panel connector

Future-proof 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.

M.2 Speed up with onboard M.2

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.

SafeSlot Protect your graphics card investment

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.

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.
