Gigabyte GA-AB350M-D3H desktop motherboard schematic, revision 1.0, provided as a PDF of roughly 1.19 MB. The AB350 designation points to an AMD B350 chipset board in micro-ATX form. Use it to follow VRM phases, standby power, the SPI BIOS circuit and the Super I/O when tracking down no-POST or no-power faults. It opens in any PDF reader. Gigabyte often releases several PCB revisions of the same model, so check the rev marking on the board near the slots before trusting component designators.
