Schematic for the MSI MS-7509 motherboard as a PDF, with the name showing 20 and 1105A, likely the revision code and a date or build stamp. MSI assigns MS-7xxx numbers to its desktop boards and prints them on the PCB. The diagrams are used to follow CPU core and memory rail generation, verify standby voltages, trace the power button path and pinpoint components by designator during short-circuit hunting. Match the revision marking on the board to the one in the title block before trusting values here.
