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 ensuring 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.

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 both your system and connected devices.

DIGI+ VRM
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.

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 (3X) longer than ordinary panels.

ESD Guards

Electrostatic discharge (ESD) can happen suddenly, and its damaging effects are easily underestimated. ASUS ESD Guards are tested to very high standards, capable of up to +/- 10kV for air discharge and +/-6kV for contact discharge. We employ an active protective circuit design to guard your system against electrostatic interference and damage, providing greater component longevity.

Media-acclaimed UEFI BIOS

The smoothest, slickest mouse-controlled graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, the EZ and Advanced Modes help you find your way, quickly and easily.

EZ Flash 3

Update the latest BIOS via the internet, and from within the BIOS.

S.M.A.R.T

Check up your storages devices' Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T) logs to gauge reliability, and even determine if they're about to fail.

Q-Fan Control

You 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!
