MSI desktop motherboard schematic for board MS-7440, revision 0A, delivered as a PDF; the trailing 1117 in the name looks like a date stamp, though its exact meaning is not stated. The drawings cover power delivery, VRM stages, clock generation and I/O connections, useful for tracing missing voltages or failed components. MSI prints the MS-xxxx code and revision on the PCB, typically near the slots, so compare both before using the document, as different revisions can differ in parts and circuitry.
