Boardview for an MSI GeForce RTX 3080 graphics card, board MS-V389 revision 5.0, in CAD format at 8.56 MB. MS-V numbers are MSI's internal codes for its graphics card PCBs. The layout helps locate VRM phases, memory supply circuits, fuses and test points when diagnosing shorted cores, missing voltages or a card that is not detected. CAD layouts like this open in standard boardview viewers; check that the revision printed on the PCB matches 5.0 because component placement changes between revisions.
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.
