ASUS announces First TUF Series Motherboard, Sabertooth 55i
Asus today has unveiled the first motherboard for The Ultimate Force “TUF” range – with the Sabretooth 55i specially designed for the power user. TUF Series motherboards undergo more stringent testing than what most other motherboards have to endure.
The Tuf series motherboard is an elite membership only award to those that meet tough military specs. This motherboards must be capable of delievering performance even under extreme conditions, they must be of Solid construction and equipped with resilient components in order to go beyound the call of duty in a moments notice. Results are the TUF Series triumphs over the harshest operating conditions to deliver robust performance.
The ASUS SABERTOOTH 55i motherboard, equipped with the new CeraM!X heatsink, delivers exceptional cooling to active components and uncompromising system stability even under intense operating conditions. With its advanced ceramics-based composition—commonly used in the aerospace industry for heat insulation—the heatsink dissipates heat rapidly to achieve ultimate cooling. Ceramics replace traditional anti-oxidant compounds to create a microfin surface texture for enhanced cooling. This rough surface offers an expanded area for heat induction into the surrounding air. As a result, more heat is rapidly conducted away from the active system—allowing users to enjoy previously unattainable levels of stability.
As optimal memory operation relies on good cooling, the SABERTOOTH 55i motherboard includes the CoolMem! Fan Frame that encloses most standard 40mm or 50mm computer fans and fits them directly over the memory module. Users thus gain an affordable cooling solution that significantly stabilizes memory operation.
The SABERTOOTH 55i is available now at authorized ASUS resellers with an MSRP of $219 USD.
