Schematic in PDF for the ASUS PRIME B660M-A AC D4 desktop motherboard, the DDR4 version with wireless, as stated in the name. Use it in any PDF reader to trace VRM phases, chipset and standby rails, follow power-on signals and identify components on the PCB. It is helpful for diagnosing no-power, no-POST or shorted-rail faults. The name gives no revision, so compare the revision silkscreened on your board with the one in the schematic title block before relying on specific values.
