Schematic for a desktop motherboard listed as Foxconn RX780A01 with the A78AX-K model name, built on the AMD RX780 northbridge with the SB700 southbridge, supplied as a PDF in a RAR archive. It is handy for checking the CPU VRM, memory power, chipset rails and the ATX power-on path while hunting shorts or a no-boot fault. Check the model and revision silkscreened on the board, because similar Foxconn AM2 boards share layouts but differ in detail.
