Schematic in PDF for the MSI GTX 780Ti Gaming 3G graphics card, labelled V298, which is MSI's internal board design number. The diagram covers power delivery, GPU, GDDR5 memory and display output circuits, readable in any PDF viewer. Technicians use it to trace rails from the PCIe connectors through the VRM, check expected voltages and component values and understand enable and power-good sequencing. Match the V298 code printed on the PCB before trusting values, as MSI reuses names across different board designs.
