Schematic in PDF for the ASUS H81M-P PLUS, an Intel H81 chipset desktop motherboard, sized 850 KB. The file name does not include a revision. Use it to trace the CPU VRM, DDR3 supply, chipset rails and the Super I/O logic that handles power switching, as well as the SPI BIOS chip wiring. It is helpful when a board shows no standby power, no post or a shorted rail. Open it in any PDF viewer and confirm the revision silkscreened on the PCB before comparing measured values.
