Schematic for the MSI PH61A-P35 desktop motherboard in its B3 stepping version, board number MS-7732, version 1.1. B3 commonly refers to the corrected H61 chipset stepping. The document shows the CPU VRM, DIMM power, the chipset rails and the SPI BIOS connection, which helps with no-power, no-POST and shorted-rail repairs. Open it in a PDF reader and follow nets between pages. Confirm the PCB is labelled MS-7732 ver 1.1 before relying on component values.
