Boardview for the MSI graphics card on PCB MS-V389, revision R6.1, a design shared by GeForce RTX 3080 and RTX 3090 models. The .brd layout lets you search any part reference or net and see where it sits on both sides of the board, which helps when locating VRM phases, memory power components, fuses and test points around the GPU. Open it in a boardview viewer such as OpenBoardView or FlexBV. Check that the revision silkscreened on the PCB reads R6.1 before trusting component positions, because placement can shift 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_schematics. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
