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

SafeSlot Core

Fortified PCIe slot prevents damage
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.

LANGuard

Pumped-up throughput. 2.5x higher surge tolerance.
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput, plus electrostatically guarded and surge-protected components for greater tolerance to static electricity and improved protection against surges.

Overvoltage Protection

World-class circuit-protecting power design
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.

ESD Guards

Electrostatic discharge protection
ASUS ESD Guards prevent damage from electrostatic discharge, up to +/- 10kV for air discharge and +/- 6kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.

Proven Compatibility

Tested to be compatible with 1,000+ CPUs, DDR4 memory modules, graphics cards and more
Having the freedom to pick and choose the parts that go into your machine is at the heart of PC DIY.

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. Fan Xpert even includes Auto-Tuning mode to scan and detect all fan characteristics for single-click customization!

Gaming Audio

Combined onboard features deliver elevated audio
Intelligent design and premium hardware create audio quality unlike anything you've ever experienced! Audio shielding ensures precision analog/digital separation and greatly reduced multi-lateral interference. Separate layers for left and right tracks ensures both channels deliver consistent, equal quality. Premium Japanese audio capacitors provide warm, natural, and immersive sound with exceptional clarity and fidelity.
