Strict compatibility and validation
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.

Precise digital power control with ASUS DIGI+ VRM
Voltage regulator modules (VRMs) are among the most essential motherboard components. A good VRM intelligently delivers CPU power based on actual needs at any given time. ASUS was first with digital power design featuring faster sensing and response to deliver precise CPU power on demand. This great accuracy reduces energy waste and of course improves system stability thanks to more consistent delivery.

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.

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.

Tested - 1,000+ compatible CPUs, memory modules, graphics cards and more
Every ASUS motherboard is compatible with thousands of devices. Our engineers fit and assess both server and consumer CPUs, hundreds of memory modules, dozens of graphics cards, loads of storage devices, power supplies, network devices, displays, optical drives, peripherals and many more. We do this to give you complete confidence in our products and their superb compatibility.

Complete & Public QVL
View our Qualified Vendor List (QVL) online
We're so confident in our motherboards' superior compatibility that we publish our entire QVL for all to see — delivering you more choices for worry-free PC-building experiences. There are no gaps in our QVL: every compatible component is on the list for all to see. To check that a particular component or device is compatible with your motherboard, just reference the QVL for instant reassurance.

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!

Ultimate cooling and quietness with Fan Xpert 2
ASUS Fan Xpert intelligently allows you to adjust CPU and case fan speeds according to different ambient temperatures in diverse climate conditions and locations, as well as actual PC loading. Various preset fan performance profiles offer flexible fan speed controls to achieve a quiet and cool environment.

Ultra-fast, always!
10Gb/s USB 3.1 built in to the board
With the latest USB 3.1 connectivity built in and Type A & Type C ports for the very fastest USB data transfers, you'll experience data-transfer speeds of up to 10Gbit/s — or twice as fast USB 3.0. The next-generation standard is completely backward-compatible with your existing USB devices, and you'll be all set for USB 3.1's breakneck speeds. And ASUS-exclusive USB 3.1 Boost technology automatically accelerates USB 3.1 performance even further!

ASUS USB 3.1 Type C– Any Way Up! The world's first USB 3.1 Type C on the board.
Traditional USB both brilliantly simple and deeply frustrating. Everything just works but getting plug in into the socket the right way up never seems to happen first time– you twist, turn, and twist again. Exclusive ASUS USB3.1 Type C any-way-up design eliminates this problem, so you'll make your USB connections first time, every time!
