Boardview archive for the MSI Z790 Carbon desktop motherboard, model MS-7D89, revision 1.2. The layout shows component placement, nets and test points for this Intel Z790 board, which helps when chasing a short on the CPU VRM, a missing standby rail or damaged traces around the socket and slots. Extract the RAR and open the file in a boardview program such as OpenBoardView or FlexBV. MSI marks the revision on the PCB near the model number, so check that it reads 1.2 before comparing positions.
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 @BoardSchematic. Enginerys does not host this file.
