The EVGA NVIDIA SLI Bridge is a 2-way graphic card connector board designed for use with EVGA and any normal motherboards. Made in the United States, this fully working bridge board has dimensions of 110mm in height, 110mm in length, and 55mm in width. With a single unit quantity, this product allows users to connect two graphic cards for improved performance in their computer setup. Perfect for those looking to enhance their system's graphics capabilities, the EVGA NVIDIA SLI Bridge is a reliable and efficient component for achieving smooth and seamless multi-card function. Fell free to ask any questions this item as been fully tested and found to be working. The reason I’m selling this is because it’s too big for my motherboard to fit any more GPUs. Thanks
