Gigabyte Ge Force GTX 960 4GB GDDR5 Dual-link DVI HDMO Display Port PCI-E Grpahics Card Powered by NVIDIA Ge Force GTX 960 GPU Integrated with industrys best 4GB GDDR5 memory 128-bit memory interface BASE: 1190 MHz / BOOST: 1253 MHz (1216/1279 MHz in OC Mode) Features Dual-link DVI-I / Dual-link DVI-D / HDMI / Display Port System power supply requirement: 400W (with one 6-pin external power connector) GIGABYTE introduces WINDFORCE, the latest cooling technology that differentiates the brand’s graphics cards from the rest. GIGABYTE understands that a fan is crucial to the graphics card, so only the fan with the most efficiency is selected for WINDFORCE. The airflow is spilt through the triangle design at the fan edge, & is guided smoothly through the fan by special 3D stripe curve design. At the same time, it effectively enhanced the cooling capacity while reducing air turbulence. Equipped with pure copper heat pipe direct touch (HDT) technology, delivering superior cooling capacity & heat transfer efficiency at an extremely low noise level.
