Schematic in PDF form for the ASUS PRIME B450M-A II desktop motherboard, packed in a 1.15 MB RAR archive; the name also carries an RG suffix whose meaning is not stated. On an AM4 B450 board like this, the diagrams help trace VRM phases, standby rails, memory power and front-panel signals when diagnosing no-power or no-boot faults. Any PDF reader opens it after extraction. Compare the revision printed on the PCB silkscreen with the drawings before relying on component values.
