NVIDIA reference schematic for the GeForce RTX 3090 on the GA102 GPU, board project PG136-A03, revision B, distributed as a 2.22 MB PDF. Reference designs like this show the original power architecture, memory layout, PCIe and display circuitry, and are useful even for many partner cards built around the same PG platform. A technician can trace rails, read controller pinouts and expected values, and understand power sequencing. Partner boards often change parts, so cross-check against the actual card before replacing anything.
