Version 1.0 circuit diagram for the MSI MS-7399 mainboard, marked 01S, which likely identifies the first in a series of related files alongside 02S and 03S. The PDF is about 1.1 MB. The MS-7xxx pattern is MSI's desktop board numbering. A technician uses it to follow the power path from the ATX connector, check standby and CPU core rails, and isolate shorted components. Compare the sibling files to see how they differ, and make sure the board is printed with revision 1.0.
