Documentation archive for the MSI Z370 GAMING PLUS desktop board, MS-7B61 at revision 1.0, packed as a 1.15 MB RAR. The model name indicates the Intel Z370 chipset, and MS-7xxx is MSI's numbering for desktop motherboards. Contents are not named, so unpack with WinRAR or 7-Zip to see whether schematics, boardview data or both are included. Use them to follow CPU VRM and memory rails, check standby power and front panel signals and find shorts. Match the revision on the board to 1.0 first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
