Boardview for MSI motherboard MS-7821 at revision 2.0, in CAD format at 5.12 MB. MS-7xxx is MSI's standard desktop board numbering. The file maps component placement, designators and nets so a technician can locate MOSFETs and controllers in the VRM, follow a rail toward its load, find test points and identify parts surrounding a short. CAD layouts open in common boardview viewers. Several revisions of a board can exist, so check the revision silkscreened on the PCB before trusting it.
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 @boardviews. Enginerys does not host this file.
