Circuit diagram for the MSI MS-7C77 desktop board at revision 1.3, packaged in a 1.91 MB RAR archive holding a PDF, alongside the reference 00205363. As the latest of the three versions in this catalogue, it should only be used when the silkscreen on your board reads 1.3. Search the PDF for net labels to follow the standby and main supply rails, check the VRM phase circuitry, and identify test points and components around the chipset and SPI BIOS chip when diagnosing no power or no display.
