The motherboard is equipped with one PCI Express x16 (Gen3.0) slot, making it compatible with modern GPUs, including the popular Nvidia GeForce GTX 1080. For optimal performance, it is recommended to pair this with a powerful processor, such as a Core i7, and a quality power supply unit (PSU) with sufficient connectors and wattage. The board is also used with GPUs like the Nvidia GeForce GT 640 and Radeon HD 8570.
