ASUS Prime is the next evolution of the ASUS motherboard, born of a pedigree that stretches back to 1989. Our team of world-class engineers are passionate about empowering everyone to enjoy the benefits of customization and tuning, and the driving force behind the development of Prime is to make advanced enthusiast controls easily accessible — maximizing performance, stability and compatibility for the very best DIY PC experiences. Simply stated: it’s time for Prime.

PRIME A320 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 motherboard. That means exceptional protection and stability for your build — thanks to decades of engineering experience from the world’s leading motherboard brand.

Overvoltage Protection

An exclusive circuit design with built-in voltage regulators to protect your chipset, connectivity ports, and audio codecs from damage caused by unexpected high-level voltages from unstable or inferior power supplies



Precision control for stable power
ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.

DRAM Overcurrent Protection

Short-circuit damage prevention
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.

Stainless-Steel Back I/O

3x corrosion-resistance for greater durability
Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that’s three times longer than ordinary panels.

Great Compatibility with ASUS Products

ASUS offers a suite of proprietary components — graphics cards, sound cards, optical drives — that perfectly complement Prime A320 series, so you can complete your custom motherboard build with confidence!

DDR4 Support

With DDR4, you’ll accelerate memory frequencies up to an incredible to 3200MHz! And ASUS works with almost every DDR4 memory vendor, so you’re assured the best compatibility.

Fan Xpert

Dedicated CPU and case fan controls

Exclusive Fan Xpert ensures every fan achieves the best balance of cooling performance and low noise – and with Prime A320 series boards and their hardware-level 4-pin/3-pin PWM/DC mode for case fans, a simple BIOS adjustment lets you run your case fan in PWM/DC
