Description

From the original post:

MSI schematic for the MS-7A40 desktop motherboard, revision 20, supplied as a RAR archive of about 1.4 MB containing a PDF. The schematic lets you trace power rails, enable signals and the paths between chips, which is useful when a board shows no power or fails to start. Check that the board number and revision printed on your motherboard match MS-7A40 VER 20 before relying on the drawings, since the same model name can appear on different revisions.

For board MS-7A40 the catalog also has 3 schematics.
