Schematic for the NVIDIA GeForce RTX 3080 reference board, GA102 GPU, PCB PG133-A03 revision A, provided as a PDF inside a RAR archive of about 1.9 MB. Use it to trace the multi-phase core and FBVDD memory regulators, the power input and current sensing, PCIe slot power, GDDR6X routing and the fan and LED headers. Many custom RTX 3080 cards borrow parts of the PG133 design, so the document is a useful reference, though the board number and revision on the actual card should be checked first.
