The most noticeable thing about the ASUS P67 SABERTOOTH is the board's thermal armor, partly because it's so different and partly just because of how cool it is. The SABERTOOTH is a full ATX motherboard and utilizes a ton of features unique to ASUS. These include the board's TUF Thermal Armor, TUF Thermal Radar, TUF Engine Power Design, 8+2 Digital Phase Power Design, TUF Components, ASUS DIGI+ VRM Utility, E.S.P. (Efficient Switching Power Design), Safe & Stable Guardian Angel, ESD Guards, MemOK!, and Anti Surge protection.
