Schematic for the MSI MS-7246 board with the revision tag 2B, saved as a 1.10 MB PDF. MS-7xxx is MSI's desktop motherboard numbering, and one model can go through several revisions with changed components. Technicians use these pages to follow the power tree, test standby and main rails, and isolate shorts on CPU or memory supplies. The 1.0, 2.1 and 2-2 versions are also listed, so check the PCB revision first and pick the drawing that matches it.
