Schematic for the MSI Z77A-G43 desktop motherboard, board number MS-7758, revision 1.0, supplied as a 947 KB PDF. The Z77 chipset places it in Intel's LGA1155 generation. Repair technicians use the diagrams to follow CPU VRM, memory and chipset power rails, standby circuits and the power-on sequence, and to find component values on a damaged board. Any PDF reader opens it. MSI prints the MS-7758 number and revision on the PCB, so compare them before trusting the drawings, as later revisions may differ.
