TUF PROTECTION
SafeSlot
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured via a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
ESD guards
ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10 kV of air discharge and +/- 6 kV of contact discharge — greatly surpassing the respective industry standards of +/- 6 kV and +/- 4 kV.
Keyboards and Mouse connectors
Additional on-circuit ESD transient-voltage-suppression.
VGA protection
Additional on-circuit ESD TVS diodes to protect VGA output functionality.
USB connectors
TVS diode for surface-mount and dual in-line package.
TUF LANGuard
TUF LANGuard is a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, protecting the motherboard from lightning strikes and static electricity.
DRAM overvoltage protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.
Stainless-steel back I/O panel
TUF Gaming motherboards have a corrosion-resistant stainless-steel back I/O panel bonded with chromium oxide to provide a 3X longer lifespan versus traditional panels. With this protective feature, TUF Gaming motherboards passed 72-hour salt fog testing, while other brands only passed 24-hour testing.
BIOS FlashBack
BIOS FlashBack is the simplest and safest (UEFI) BIOS update method. Simply drop the (UEFI) BIOS file onto a FAT32 formatted USB stick, plug it into the USB BIOS FlashBack port and press the button. Updates can even be performed without having memory or a CPU installed.
Armoury Crate
Armoury Crate is a new software utility designed to give you centralized control of supported gaming products. From a single intuitive interface, Armoury Crate lets you easily customize RGB lighting and effects for every compatible device in your arsenal and synchronize them with Aura Sync for uni?ed system lighting effects. You can also turn on the AI Noise-Canceling Microphone function for crystal-clear in-game voice communication.
