MSI MS-7A12 schematic at revision 1.1, provided as a PDF in a 1.69 MB RAR. MSI uses MS-7xxx numbers for its desktop motherboards, and this board number is printed on the PCB near the slots along with the revision. The diagram helps follow the CPU and memory VRM rails, standby power, Super I/O and BIOS wiring, and front panel connections when hunting faults such as no power or shorted phases. Check the revision on the board, since other versions may use different components.
