PDF schematic for the ASUS Q87M-A desktop motherboard, packed in RAR; the TYCO-SI and RG tokens in the name are not expanded here. A schematic shows the circuit pages for power rails, VRM stages, the chipset, memory and I/O, which helps a technician trace a missing voltage, find the source of a short or check enable and power-good signals. Use any PDF reader with text search for net names. Confirm that the board revision printed on the PCB corresponds to this document before trusting values.
