      ASUS Expedition: Ready for non-stop battle
      ASUS Expedition motherboards are made for non-stop action, engineered with non-stop durability to prevent damage from moisture, corrosion and overvoltages — for immense longevity. We even test them to the limits, with 144 hour of diskless-system tests and extensive checks for compatibility with top games and over 100 gaming peripherals. And for the ultimate audio, Expedition motherboards have Audio feature to provide exhilarating non-stop gaming performance — and the best stability, reliability, and value for you!
      Exceptional stability and protection
      ASUS Expedition motherboards offer an exclusive package of unbeatable hardware and features to ensure non-stop durability, including an anti-moisture coating, gold-plated PCIe® x16 slot and LAN connector, USBGuard protection for 120%-higher overvoltage toleration, and exclusive 5X Protection II for absolute reliability.

      Anti-moisture coating

      100% protection against moisture and corrosion
      This innovative moisture-resistant coating provides 100% motherboard protection, and combats the higher levels of humidity that build up in densely-populated environments, such as internet cafes, libraries and data centers. It even minimizes internal corrosion by preventing the adhesion and migration of moisture — prolonging the life of your Expedition motherboard.

      Gold-plated PCIe x16 and LAN design

      Up to 6X-stronger durability
      ASUS Expedition motherboards are equipped with a premium 30-micron-thick gold-plated LAN connector, and a 15-micron-thick gold-plated PCIe x16 port to protect your investment against corrosion, and improving durability and reliability.


      120% higher overvoltage protection
      Exclusive USBGuard technology detects voltage changes in real time, and has 120%-higher overvoltage tolerances than standard to ensure stable and reliable input voltages — minimizing the risk of damage, and protecting your equipment.

      5X Protection II

      Advanced hardware safeguards
      Industry-leading 5X Protection II employs the finest components, excellent circuit design, and exacting standards to guarantee quality and long-term durability of your motherboard with all-round protection. For you, that means exceptional protection and stability for your build — the result of decades of engineering experience from the world's leading motherboard brand.

      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

        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.

      • DIGI+ Voltage-Regulator Module

        The 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

        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.

      • Stainless-Steel Back I/O

        Corrosion-resistant stainless steel back I/O panels bonded with chromium oxide have a lifespan that's three times (3X) longer than ordinary panels.

      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.
