Asus TUF Z270 Mark 1 Review


The Asus TUF series of motherboards has been with us for some time now. The first in the series was the Sabertooth X58 that arrived in 2010. Its military look and tough image quickly caught the imagination of many system builders and enthusiast alike. The series really took off when Asus released the Sabertooth P67, which features their Thermal Armor. Modders jumped on this new motherboard, often modifying and/or painting the Thermal Armor to match their builds. Fast forward to 2017 and we have the latest iteration of TUF design, the TUF Z270.

The TUF series Z270 motherboards comes in two flavors, the Mark 1 and Mark 2. The Mark 2 is the more affordable version and sans the Thermal Armor. The Mark 1, which we will be reviewing here, has the Thermal Armor. Both tout military styling and that look is more than just cosmetics, Asus’ goal was ultra-reliability. Asus manufactures its TUF series with some of the most rigorous requirements seen in any consumer level motherboard.

The TUF Z270 Mark 1 is manufactured with many unique features not found on other product.  There’s a dedicated processor that monitors onboard temperature sensors and fan speeds. Multiple onboard sensors also let the user monitor onboard temperatures. The TUF Fortifier, a reinforced motherboard backplate. That tough theme is backed up by SafeSlot Core fortified PCI-E slots, TUF Alloy Chokes, TUF Capacitors, TUF MOSFETs, TUF ESD Guards 2, TUF LANGuard, and of course that TUF Thermal Armor. Cooling is covered by a staggering ten fan / water pump/ accessory fan headers, combined with Asus’ Thermal Radar 2+, keeps everything cool. The key word here is TUF.

The TUF Z270 Mark 1 isn’t just about being tough though, Asus has added a host of other features. Being built on the Z270 chipset, there’s support for both 6th and 7th Generation Intel Core processors. Dual Turbo M.2 connectivity with transfer speeds up to 32 Gb/s with support for Intel Optane technology. Six SATA ports offer even more storage options. The four DDR4 memory slots memory that can handle up to 64GB and at speed all the way up to 3866Mhz. The Intel i219V and i211 chips provide high quality network dual connectivity. Two USB 3.1 front panel connectors along with two USB 3.1 rear ports handle the high speed USB connectivity needs.  A full software suite and robust overclocking features round out that package.
