Schematic diagram set for a GeForce RTX 3080 based on the GA102 GPU, following NVIDIA's PG133-A03 board design at revision A and supplied as a PDF in a RAR archive. Many partner cards derive from this layout, so it is a useful reference for the NVVDD and FBVDD power stages, the PEX and display interfaces, and the sequencing signals. Use it to locate the enable, power-good and feedback nets while checking for shorts or a dead controller. Confirm that the PG code on the PCB matches, since partner boards often differ in detail.
