Schematic for board MS-7392, version 2.0 as shown by v20 in the name, which follows MSI's MS-xxxx numbering though no brand is stated. Version 1.1 of the same board also exists and may differ, so check the version printed on the PCB. The PDF helps follow CPU VRM phases, DIMM and chipset supplies, standby power and the Super I/O power-on logic when a desktop board does not start, fails to post or has a shorted rail.
