PDF schematic for the MSI MS-7B45 desktop motherboard, revision 2.0 as indicated by the 7B45_20 tag, compressed to 1.63 MB. A circuit diagram for an MSI board shows VRM phases, chipset power, standby rails and front panel signals, so it supports diagnosing no-power and no-post faults with a meter. Combine it with the boardview to find parts on the PCB. Note that a 1.0 boardview also exists, so check the revision on the board, since layouts may differ between versions.
