Gigabyte GA-945PL-S3 desktop motherboard schematic for PCB revision 3.3, supplied as a PDF inside a RAR archive of about 1.06 MB. Technicians use the circuit diagram to follow power rails from the ATX connector to the VRM, check chipset and memory supply voltages, and trace signals around the Super I/O and BIOS chip when a board will not power on. Gigabyte prints the revision on the PCB near the slots, so confirm it reads 3.3 before relying on component values here, as other revisions differ.
