PDF schematic of the Gigabyte GA-Z77X-D3H, revision 1.2, inside a RAR archive of about 983 KB. This later revision can carry changes against earlier 1.0x and 1.1 boards, so confirm the revision printed on the PCB before using any values from it. Unpack it and open it in a PDF viewer to trace the VRM, chipset power, the super I/O and BIOS chip circuits, and the startup sequence. It is a useful reference when checking a shorted rail or a missing power-good signal.
