PDF schematic for MSI MS-7B28, revision 20, tagged with reference 00017967 and archived as a 1.17 MB RAR. The diagram set covers the desktop motherboard's power delivery, chipset, memory and I/O circuits, so it serves for tracing missing voltages, checking sequencing and finding values of damaged parts. MSI designates desktop boards with MS-7 numbers, and this design has many revisions, so read the one printed on the PCB before working from it.
