TUF /tΛf/, stands for The Ultimate Force.
The TUF series delivers a "tough" image. With the unique design & high quality components (military-standard), TUF series is born for pursuing the preeminent stability, all-round compatibility, and extreme durability  

AMD 990FX(AM3+) Military-Grade Motherboard with Aerospace-Grade CeraM!X Cooling Tech.
The newest addition to the TUF Series motherboards is the SABERTOOTH 990FX, which also has the distinction of being the first AMD-based system in the TUF Series of motherboards. Known for their unrivaled quality and reliability in extreme conditions, the SABERTOOTH 990FX features the use of CeraM!X, an exclusive aerospace-grade cooling material with a 50% larger cooling area that effectively conducts heat away from vital system components. Also onboard is ASUS' Thermal Radar technology, which consists of ten sensors located on various vital components, giving users the ability to monitor each one individually and automatically adjusts fan speeds to ensure the system maintains a level of high stability without overheating. TUF motherboards are also made from TUF components, which are comprised of military-certified alloy chokes, solid state capacitors and MOSFETs built to withstand the most extreme usage conditions possible for greater system stability and longevity. A TUF motherboard built with high-end components ensures quality and tested server-grade reliability and are certified TUF only after a series of extreme stress tests including maximum temperature and humidity tolerance, so users get nothing but the best and most reliable motherboard on the market.

"Ultimate COOL!" Thermal Solution

CeraM!X - Heatsink Coating Tech. 50% Larger area for heat dissipation with the revolutionary ceramics-coating technology Innovative ceramics effectively conducts heat away from the system. It replaces traditional anti-oxidant to dissipate heat better with its microscopic irregular surface and enlarged area. Better cooling leads to overall improvement in system stability.

TUF Thermal Radar Real Time Temp Detection and Heat Removal The TUF Thermal Radar monitors temps in critical parts of the motherboard in real time, automatically adjusting fan speeds to make sure the system maintains high stability without overheating. It consists of multiple sensors for various components on the motherboard, giving users the ability to monitor each one individually. The Thermal Radar automatically calculates ideal fan speeds based on different parameters selected by users for each component, keeping everything cooler and longer lasting.

"TUF ENGINE!" Power Design

	DIGI+ VRM Herald the Arrival of a New Digital Power Design Era The new ASUS DIGI+ VRM design upgrades motherboard power delivery to a digital standard. The 8+2 digital architecture provides the highest power efficiency, generating less heat to enhance longer component lifespan and ensure minimal powerloss. With ASUS DIGI+ VRM, users can easily adjust power phase performance, enabling new PWM voltage and frequency modulation controls. Digital 8+2 power phase design also expands the modulation spectrum for improved stability and lower VRM switching noise by dynamically detecting system load, empowering users with superior flexibility and perfect precision to ensure optimized performance, extreme system stability, and greater power efficiency.
	UEFI BIOS Flexible and Easy BIOS Interface ASUS UEFI BIOS offers a user-friendly interface that goes beyond traditional keyboard-only BIOS controls to enable more flexible and convenient mouse input. Users can easily navigate the UEFI BIOS with the smoothness of their operating system. Quick and simple overclocking and setup sharing is facilitated by the F12 hotkey BIOS snapshot feature. The exclusive EZ Mode displays frequently-accessed setup info, while the Advanced Mode is for experienced performance enthusiasts that demand far more intricate system control, including detailed DRAM information.
	E.S.P. Efficient Switching Power Design Optimal power efficiency for key components Exclusively for this motherboard, the switching power design is provided not only for the CPU and memory, but also for other key components such as graphics cards, LAN and USB 3.0. E.S.P. dramatically improves system efficiency and reduces heat generation.
	TUF Components (Alloy Choke, Cap. & MOSFET; Certified by Military-standard) Certified for Tough Duty Get rugged performance even in the most challenging conditions with robust TUF chokes, solid capacitors, and MOSFETs--certified through third-party, military-grade testing. TUF Chokes, also known as the "Alloy Choke", is a made of a compound of various types of metal instead standard iron, enables the support of up to a massive 40A of rated current, 25% higher than conventional component. Furthermore, the single piece packaing also elimates the emission of virbation noise, delivering superb charactoristics as well as durability under extreme conditions.

"Safe & Stable!" Guardian Angel

	MemOK! Any Memory is A-OK! MemOK! quickly ensures memory boot compatibility. This remarkable memory rescue tool requires a mere push of a button to patch memory issues. MemOK! determines failsafe settings and dramatically improves your system boot success. Get your system up and running in no time!
	ESD Guards Unique protection of motherboard components from unexpected electrostatic discharges (ESD) Electrostatic discharge (ESD) can happen suddenly and its damaging effects is often underestimated. Exclusive ASUS anti-static chip, a protective circuit design, and the I/O shield provides four times better protection to extend component lifespan.
