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 9 Series 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 9 Series 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!

Flawless audio that makes you part of the game
Crystal Sound 2

Crystal Sound 2 makes short work of optimizing audio settings for the way you want to listen, be it gaming, chatting, watching movies or relaxing to your favorite music.

Discover a whole new dimension of superior audio and get ready to rule!

Turbo LAN

Turbo LAN with cFosSpeed traffic-shaping technology adds even more lag-reducing support and intuitive user interface. It allows you to lower lag with no expert knowledge – by up to 1.45X! If you're a tweaker, use Advanced Mode for hardcore controls.

Work with up to 3 displays
Connect up to three independent monitors at once using video outputs such as DisplayPort, Mini DisplayPort, HDMI, DVI, or VGA. Choose your outputs and set displays to either mirror mode or collage mode.

4K/Ultra HD visual excellence
Native support for 4K/UHD (ultra-high-definition) resolutions of up to 4096 x 2160 via HDMI or DisplayPort —that's four times the pixel count of 1080p (1920 x 1080), offering incredible visual clarity, detail, and realism.
