MSI MS-7399 schematic at version 1.0, the file tagged 03S, which seems to mark the third part or variant of a multi-file set alongside 01S and 02S. The PDF is about 1.1 MB. MSI numbers its desktop motherboards in this MS-7xxx format. The diagrams serve for tracing power rails, checking power-good signals, and locating parts near a shorted rail. Compare it with the 01S and 02S files to make sure you have the sheets you need, and match the 1.0 revision printed on the PCB.
