Schematic in PDF format for MSI motherboard MS-7459, revision 1.0. It documents the board circuitry page by page, including CPU power stages, memory supply, chipset rails, clock and reset logic and rear-panel I/O, which helps when hunting a missing voltage or a board that will not power on. MSI marks the MS model number and revision on the PCB silkscreen; check that yours reads MS-7459 version 1.0, since component placement and values can change between revisions.
