MSI MS-7388 desktop mainboard schematic, revision 0A per the file name, packed in a compact 633 KB PDF. MSI assigns MS-7xxx codes to its desktop boards, and early revisions such as 0A can differ from later production issues in component values and layout. Use the diagram to follow the CPU VRM, memory voltage and standby rails, check the front-panel power switch path and locate parts near a suspected short. Compare the revision printed near the PCI slots or board edge with this document before relying on it.
