RAR archive of 954 KB labelled MS-V317 revision 1.1; the name does not specify the card model or whether the contents are a schematic or boardview. MSI uses the MS-Vxxx pattern for its graphics card PCBs, so this likely relates to an MSI video card board. Inspect the archive to see what it holds. Confirm that the MS-V code and revision printed on the card match 1.1, as a separate 1.0 version also exists, before using it to trace GPU core, memory and PCIe power rails.
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 @cyberlanelectonik. Enginerys does not host this file.
