Desktop motherboard schematic for the ASUS A7V8X, provided as a 9.69 MB PDF. The name states no PCB revision, so check the revision printed near the expansion slots against the document title block. A schematic of this kind lets a technician follow the CPU VRM, memory supply and chipset rails, verify capacitor and MOSFET positions around a failed regulator and trace signals from the Super I/O and BIOS chip. It opens in any PDF viewer, and searching by net name makes it easier to cross sheets.
