PDF schematic for the Gigabyte GA-P55-USB3 desktop motherboard, with REV 20 in the name, most likely meaning revision 2.0, in a 1.2 MB RAR archive. Technicians use it to follow rails from the ATX connector through the VRM and chipset supplies and to identify parts and test points around a fault. It opens in any PDF viewer. Compare the revision printed on the board with the document, because component values can differ between revisions.
