PDF schematic set for the MSI MS-7A33 desktop board, with the name pointing to revisions 2.0 and 1.0, compressed into a 1.97 MB RAR. MS-7xxx numbers are MSI's own desktop motherboard codes. Use the diagrams to trace power delivery, reset and power-good chains, the SPI BIOS connection and I/O controller wiring when repairing a dead or unstable board. Check the revision silkscreen on your PCB and choose the matching document, since 1.0, 2.0 and later versions may use different components.
