ASUS is proud to introduce the new ASUS ENGTX550 Ti DC to all our users. Using the unique ASUS Direct CU Cooler the airflow is doubled & the noise level is greatly reduced by using flattened copper heat pipes which directly contact the GPU core to speed up heat dissipation for a 20 cooler performance compared to reference. Keeping the card temperatures low also results in quieter operations thanks to reduced fan speeds brbr The card also boasts Super Alloy Power which can create a 15 performance increase 2.5 longer product life span & a 35C cooler operation. In addition to this the engine clock runs at a Pre Overclocked 910 M Hz allowing users to enjoy high speed & an unprecedented gaming experience. Super Alloy Power is a special blend of elements formed using an ASUS exclusive formula under extreme pressure & temperatures. The metals are highly-magnetic heat-resistant & anti-corrosive used to reduce power loss enhance durability & achieve cooler operation.brbr Super Hybrid Engine is an intelligent power consumption optimizer that switches between high- & low-intensity power profiles in real-time. This in turn can provide up to 15 enhanced performance. brbr With exclusive Voltage Tweak technology also being a key feature of this product the ENGTX550 Ti DC2DI1GD5 covers users for every possible over-clocking & over-volting scenario.
