Schematic for the MSI MS-7C77 motherboard at revision 1.3, delivered as PDF in a 6.05 MB ZIP archive. The MS-7C77 code corresponds to the MEG Z490I UNIFY board. Use it to trace CPU VRM phases, standby rails, enable signals and connector pinouts while diagnosing dead boards or shorts, with any PDF viewer. Before following component designators, compare the revision silkscreened on the PCB with this document, because revision 1.2 is a separate version and parts or values can change between them.
