Schematic for the MSI MS-7A75 desktop mainboard, where the 10 token in the name most likely marks revision 1.0, packed as a 1.62 MB PDF. The document covers the main power stages, clock and reset logic, SATA and USB connections and the SPI BIOS circuit. It is useful when hunting a short on the 12 V or VCORE line, checking which MOSFETs belong to which phase or verifying header pinouts. MSI uses the MS-7xxx numbering for its desktop boards, and the code printed on the PCB must match before you rely on this sheet.
