Gigabyte schematic for the GA-RP65Y9 board at revision 1.1, supplied as a 2.71 MB PDF; the (2) suffix in the name suggests a duplicate copy of the same document. A circuit diagram like this lets a technician follow power rails from the charger and VRM stages through to the load, check signal paths between chips, and identify part values around a shorted component. Any PDF reader opens it, and searching by net name speeds up tracing. Confirm the revision printed on the PCB reads 1.1 before trusting component references and values.
