Schematic in PDF format for the ECS H77H2-EM desktop motherboard, revision A, delivered in a 1.69 MB RAR. Based on the Intel H77 chipset for LGA1155 processors, it is useful for tracing VRM and standby rails, memory power, clock and reset signals when a board fails to power or post. Any PDF reader opens it after extraction. Compare the revision printed on the PCB with revision A to make sure component references and values line up.
