Schematic in PDF format for a GTX 750 Ti graphics card, based on the board code P2010-B01, which follows NVIDIA's reference PCB numbering. No card brand is given in the name. Opened in a PDF viewer, it shows the GPU, memory, power delivery and display circuitry. Technicians use it to trace rails, check component values around the VRM controller and follow power-up signals. Partner cards often modify the reference design, so compare your board against the drawing before replacing parts.
