Circuit diagram in PDF for the MSI MS-7A09 desktop motherboard, revision 1.0, document number 00017967, archived in a 1.20 MB RAR. A separate revision 1.1 file exists, so read the revision marking on your PCB before using component values. MSI identifies its boards with the MS- code printed on the PCB. Technicians use the schematic to trace standby and main power rails, check the CPU VRM controller and phases, and find the source of a short on the 12V or memory supplies.
