Media reviews
"I think the Prime X299 Edition 30 deserves our gold award for several reasons. I've tested many X299 motherboards and this is probably, if not the best of them despite its excessive price and weird market position. It also earns points for being a nice commemorative piece and something that's going to be a limited edition whether that was intentional or not. It's not perfect, but it's about as close as I've seen from any other motherboard model.”

Validation Hours Extensive testing for extreme reliability, compatibility and safety.

We are the world's biggest motherboard manufacturer, and renowned our design thinking that revolves around users – just like you. Our engineers employ exacting standards to guarantee quality throughout the product's life, choosing the finest components for real-world protection. Our motherboards are proven to be compatible with more than 1,000 components and devices, and undergo a minimum of 7,000 hours of strict validation. That gives you the peace of mind of knowing that ASUS motherboards are fit for all environments and applications. To build your PC with the best foundations, build it with an ASUS motherboard.

ASUS 5X Protection
Hardware safeguards to ensure long-term durability

Our be-the-best ethos underscores the choice of every single component that goes into your ASUS motherboard. We focus relentlessly on quality to ensure long-term system reliability and performance.

  • LANGuard for advanced LAN protection

    ASUS LANGuard socket has advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, while surge-protected and electrostatically-guarded components (ESD Guards) protect your motherboard from lightning strikes and static electricity.

  • Enhanced 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 device.

  • 5K-hr solid-state capacitors that last 2.5X longer

    Solid-state capacitors are able to withstand extreme temperatures of up to 105°C for as long as 5,000 hours — that's two-and-a-half (2.5X) times longer than traditional capacitors. This exceptional durability means superb real-world endurance to more typical PC operating temperatures, ensuring that ASUS motherboards continue working longer.

  • Stainless-steel back I/O that lasts 3X longer

    ASUS motherboard back I/O panels are made from strong and corrosion-resistant stainless steel, which is bonded with a thin layer of chromium oxide to enhance anti-corrosive properties. Passing 72-hour spray salt endurance tests, ASUS stainless steel back I/O panels have a lifespan that's three times (3X) longer compared to ordinary panels.

  • ESD Guards for protection from electrostatic discharge

    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.

Keyboard and mouse connectors: Additional on-circuit ESD transient-voltage-suppression (TVS) diodes.
D-Sub connectors: Additional on-circuit ESD TVS diodes to protect
D-Sub functionality.
USB 3.0 connectors: On-circuit TVS diodes for surface-mount and dual-inline packages.
LAN port: LANGuard protection on the LAN circuit.
USB 2.0 connectors: Varistor protection on back audio-output circuits.
Proven compatibility

Having the freedom to pick and choose the parts that go into your machine is at the heart of PC DIY. Our extensive certification program focuses on providing the very best compatibility with the widest range of components and devices, giving you the freedom to build and upgrade without frustration. Compatible today and compatible far into the future – that's the ASUS way.

Designed — Great compatibility with ASUS products

When you choose an ASUS motherboard, it's likely you'll also go with ASUS for other components. ASUS designs products from the ground up so that graphics cards, sound cards and optical drives work flawlessly with your motherboard.

Top-to-bottom reliability

Our motherboards have superb endurance. We verify this by subjecting every board to over 7,000 hours of stringent tests. A barrage of burn-in, environmental, compatibility, software and safety tests confirm that our motherboards are exceptionally robust — with reliability that surpasses industry standards.

Extensive testing for extreme reliability, compatibility and safety

Each motherboard is subjected to extended reliability testing under heavy load conditions, from the transportation to daily operations, to make sure they are delivered to you in perfect condition. Trials include temperature and humidity, burn-in, power on/off, power consumption, insertion and thermal-shock testing among many others. Every certified-compatible component puts through an up to 24-hour aging test to ensure trouble-free operation every day – no matter what you fit or attach and no matter what you do!
