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

Fan Xpert 2+
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.
Energy Efficient Design
With the Energy Processing Unit you'll enjoy system-wide power savings - with CPU-wattage reductions of up to 12W*! The EPU automatically optimizes power consumption and maximizes savings with Away mode: A setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers and reducing power to the graphics cards while you're away.
Intel Optane Memory Ready
Intel® Optane™ Memory* is a revolutionary (non-volatile memory) technology supported by Prime 200-series motherboards. Intel Optane Memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
*Supports 7th Generation Intel® processors. Requires driver and BIOS update.
Speed Up with Onboard M.2 Up to 32Gb/s
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gb/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible.
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!
