Circuit diagram for the Gigabyte GA-Z77-D3H motherboard, revision R10, saved as PDF and compressed into a 928 KB rar. The model uses the Intel Z77 chipset, and the schematic documents its power delivery, clock and reset chain, memory slots, expansion slots and rear I/O. It is useful for measuring standby and main rails, checking MOSFETs in the CPU VRM and tracing why a board fails to power on. Several revisions of this board exist, so match the 1.0 revision silk-screened on the PCB with this document.
