TUF motherboards use high-durability components such as Japan-made 10K Black Metallic capacitors, which support 20% greater extreme temperature tolerance and five times the lifespan of generic capacitors. TUF-specific features include Thermal Armor motherboard covers, which have been revamped with an airflow-boosting flow valve design on SABERTOOTH Z87, while TUF Fortifier backplates reinforce motherboards against bending and bowing, ensuring longer-lasting PCs. Dust Defender adds special enclosures that protect expansion slots and connectors against debris accumulation, also promoting greater system longevity.
