EMI cover


Overvoltage Protection
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.

DRAM Overcurrent Protection

Short-circuit damage prevention
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 devices.


Precision control for stable power
ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.

Stainless-Steel Back I/O

3X corrosion-resistance for greater durability
Corrosion-resistant stainless steel back I/O panels bonded with chromium oxide have a lifespan that's three times (3X) longer than ordinary panels.
ESD Guards
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.
LAN port
ESD TVS diode protection on the LAN circuit.
USB connectors
TVS diodes for surface-mount and dual-inline packages.
VGA connectors
Additional on-circuit ESD TVS diodes to protect D-Sub functionality.
Keyboard and mouse connectors
Additional on-circuit ESD transient-voltage-suppression (TVS) diodes.
Superb Performance
DDR4 Overclocking strength in numbers
ASUS 2nd generation T-Topology enables DDR4 memory overclocking to reach new heights: over DDR4-3466 MHz with all memory slots populated. Featuring a customized trace layout for reduced crosstalk and coupling noise, ASUS 2nd generation T-Topology ensures time-aligned signal transfer for improved memory stability and compatibility.
Media-acclaimed UEFI BIOS
The smoothest, slickest mouse-controlled graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, the EZ and Advanced Modes help you find your way, quickly and easily.
EZ Flash 3
Update the latest BIOS via the internet, and from within the BIOS.
Check up your storages devices' Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T) logs to gauge reliability, and even determine if they're about to fail.

Ultrafast Transfer Speed
SATA Express
Current SSDs devour up to 550MB/s bandwidth, which is close to saturation point for SATA 6Gbit/s connections. Backwardly compatible with up to two SATA drives, SATA Express is the next-generation connectivity standard — and ensures that you and your system won't get left behind.
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbit/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.
10Gbit/s USB 3.1 onboard
With USB 3.1 Type-A port, you'll experience data-transfer speeds of up to 10Gbit/s — or twice as fast USB 3.0. USB 3.1 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!
Instant front-panel USB 3.0 Experience
We've put USB 3.0 right where you need it — four 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 (USB-C) delivers future device compatibility and high-speed USB connectivity of 5Gbit/s from a slim, reversible port.

  • 1/3 smaller
    — than traditional USB Type-A
  • Reversible ease
    — any-way-up design means USB connections are made first time, every time
