Gigabyte GA-P55-USB3 schematic for revision 1.0, delivered as a PDF in a RAR archive of about 1.2 MB. The diagrams show power sequencing, VRM controllers, voltage rails, connector pinouts and part values, which help when diagnosing a desktop board with no power or no POST. Any PDF reader opens it. Since the model exists in several revisions, check that the PCB marking reads 1.0, as later revisions may use different circuits.
