Gigabyte GA-P55A-UD3 schematic, apparently for revision 1.0B, supplied as a PDF in a 1.22 MB RAR archive. The P55A-UD3 is an Intel P55 chipset board, and the A suffix marks the variant rather than the UD2 micro-ATX models. The drawings help trace CPU and memory power, chipset rails and peripheral signals, and pinpoint components on a shorted line. Open it with any PDF viewer. Check the revision printed near the PCIe slots or board edge before relying on component references.
