Schematic in PDF for the MSI MS-7878 desktop motherboard, revision 1.1, supplied in a 1.59 MB RAR archive. The circuit diagrams cover the power sequencing, VRM, chipset and I/O sections, letting a technician follow signals, look up component values and understand power-on logic when a board will not start. MSI desktop boards carry the MS-7xxx code and revision on the PCB, so confirm both match revision 1.1. Use it together with the matching boardview to find physical parts quickly.
