Schematic package for a GeForce RTX 3080 graphics card built around the GA102 GPU, reference PCB PG133-A03, Rev A, supplied as PDF inside a 1.87 MB RAR archive. PG133 is NVIDIA's internal board code for its GA102 reference design, and partner cards built on that layout share much of the circuitry. Technicians use it to follow VRM phases, memory power, PCIe and display output signals while diagnosing shorts or missing rails. Confirm the PCB code and revision on the card match before relying on it.
