Prime 200 motherboards are engineered with industry-leading 5X Protection III, employing the finest components, excellent circuit design, and exacting standards to guarantee the quality and long-term durability of your motherboard. That means exceptional protection and stability for your build — thanks to decades of engineering experience from the world's leading motherboard brand.

  • 5X Protection III: Multiple hardware safeguards for all-round protection
  • Dual native M.2: Lightning-fast storage speeds
  • USB Type-C: Convenient reversible connectivity
  • Intel® Optane™ memory ready: Exploit the latest high-speed storage technology

Fortified PCIe with solid soldering
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.

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 to ensure 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.

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.

Electrostatic discharge protection
ASUS ESD Guards prevent damage from electrostatic discharge, up to +/- 10kV for air discharge and +/- 6kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.

Tested to be compatible with 1,000+ CPUs, DDR4 memory modules, graphics cards and more
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.

DDR4 Support
With DDR4, you'll accelerate memory frequencies up to an incredible to 2400MHz! And ASUS works with almost every DDR4 memory vendor, so you're assured the best compatibility.

Advanced fan controls

With onboard thermal sensors and hardware-level 4-pin/3-pin PWM/DC mode detection, Fan Xpert 2+ makes sure every fan achieves the best balance of cooling performance and low noise!

  • Auto-Tuning Mode: Scans fan parameters and all fans with a single click.
  • Extreme Quite Mode: Reduces the CPU fan speed to below the default minimum, for extra-quiet operation and power savings during light loads.
LED-illuminated control for trace paths
Built-in LED lighting options illuminate your build in a variety of eye-catching styles.

Combined onboard features deliver elevated audio 
Intelligent design and premium hardware create audio quality unlike anything you've ever experienced!

Instant front-panel USB 3.0 Experience
We've put USB 3.0 right where you need it - two super-speed ports on the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, so no more back-breaking contortions in the hunt for hard-to-reach rear ports!

USB Type-C for convenient connectivity

USB Type-C delivers futureproof device compatibility and high-speed connectivity, enabling data rates of up to 5Gb/s. Along with being 33% narrower and nearly 50% slimmer than traditional USB Type-A ports, the USB-C features a fully reversible port design — so connections are made the first time, every time.
