MSI schematic in PDF format for board MS-7C77 revision 1.2, compressed in a 6.14 MB ZIP archive. MS-7C77 is the code MSI uses for the MEG Z490I UNIFY motherboard. The circuit diagrams let a technician follow VRM and standby power rails, check the power-on sequence, identify component values and trace signals when hunting a short or a no-POST fault. Any PDF reader opens it; check the revision printed on the PCB, since revision 1.3 also exists and component details may differ.
