MSI MS-7B87 schematic, revision 1.1, distributed as a PDF in a 1.46 MB RAR. MS-7xxx is MSI internal numbering for desktop boards, and the retail name is not stated in the file name. Use the diagrams to follow power rails from the ATX connector through the VRM, check enable and power-good signals and identify components around a shorted line. Compare with the revision silkscreened on the board, since the 1.0 schematic differs, and pair it with the 1.1 boardview for physical locations.
