Power sequence document for the Gigabyte GA-H81M-DS2 desktop motherboard, revision 1.0, compressed in a small RAR archive. It describes the order in which standby and main rails, enable signals and power-good lines come up from plugging in to CPU reset release. Technicians use it to measure each step with a multimeter or scope and find where startup stops on a board that will not power on. Make sure the revision printed on the board matches before relying on the timing.
