- I hopefully have a schematic that closely matches this board (there are differences), I also have another working almost identical MSI GTX 1650 (different in that no extra PCI-E cable)
- Not sure what order the missing rails come up in, so perhaps best to start by investigating PEX or Vcore.
- Possible physical damage / dislodged capacitor near PEX buck converter.
