Don't let slow networking disrupt your workflow! With dual Intel® Gigabit Ethernet connectors, TUF Z270 Mark 1 keeps your data moving swiftly and efficiently. With both LAN ports teamed* you'll benefit from increased bandwidth for more speed, automated load balancing for smoother data flows, and instant failover if something should go wrong — so access to your files is always fast, efficient and uninterrupted.

*Teaming supported by Windows 7 or 8.1 and dual Intel Ethernet only.



The total cooling commander

ASUS TUF engineers have forged TUF ICe, a dedicated processor that monitors onboard temperature sensors and fan speeds for ultra-accurate cooling — whether you're adjusting settings manually or using the automatic one-click optimization via Thermal Radar 2+ and TUF Detective 2.

Thermal Radar 2+

Instant fan tuning, complete system cooling

Thermal Radar 2+ lets you control fans on ASUS graphics cards as well as your case fans! Multiple onboard sensors also let you monitor onboard temperatures and other key components in real time – so you can make adjustments manually or optimize automatically, with a single click.

TUF Thermal Armor

Stylish and strong protection

TUF Thermal Armor is a strong, futuristic shield with built-in Aura RGB illumination that adds eye-catching aesthetics to your TUF Z270 Mark 1 system. It looks great and offers another way to keep things cool. Just connect an additional fan* to boost airflow to the heat-sensitive voltage-regulator module — this reduces area temperatures by up to 18.9° C.

*Supports 40mm fan (sold separately)

TUF Detective 2

System management at your fingertips

A free ASUS app allows you to track vital system information and make system settings adjustments from your smartphone or tablet. Detect and diagnose errors, adjust system settings, or monitor and control fan settings via the app — without turning on your PC!


You demand 24/7 reliability — and we've delivered! TUF motherboards undergo the industry's most punishing tests to ensure they're ready for long-term duty in any environment. In our tests we overheat them, chill them, bend them, shock them and drop them — so you know that your TUF motherboard is certified for 24/7 reliability!

5-Year Warranty, Guaranteed Reliability

*The service will follow the local standard and service policy.

TUF Fortifier

Tougher backplate, tougher board

TUF Z270 Mark 1 delivers great strength via the exclusive TUF Fortifier — a reinforced backplate that ensures that the motherboard doesn't buckle under the weight of heavy graphics cards and CPU coolers, minimizing the risk of damaged circuitry from bowing and bending.

Dust Defenders

Repel dust, extend lifespan

TUF Z270 Mark 1 has unique Dust Defenders to prevent dust and other airborne particles from entering the motherboard's PCI Express® expansion slots, helping your PC perform in an optimal and stable state for longer.

ASUS SafeSlot

SafeSlot is the PCIe® slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process to integrate the slot with fortifying metal support, the slot is then firmly anchored to the board through additional solder points.

TUF Components

Certified for tough duty

  • TUF Chokes - Certified military-grade TUF chokes offer unbeatable durability in order to maximize the lifespan of your system.
  • TUF Capacitors - +110% temperature, tolerance and 1.5X-longer lifespan.
