## Key points

- An RTX 5090 owner found a blackened power cable.
- A replacement monitor also flagged unusual current on pin four.
- Monitoring devices cost less than a potential card replacement.

## Summary

A reported RTX 5090 owner found the power cable blackened at the power supply end after a monitoring device repeatedly flagged unusual current on one pin. The case highlights continued reports of melting 12+4-pin cables and the potential value of checking connections on costly high-end graphics cards.

The owner bought the card in June and replaced the WireView Pro II monitor after its readings were dismissed as a possible fault; the replacement showed the same issue on pin four. After changing the cable and using the GPU’s other power port, they said the problem had not recurred. The article lists monitoring options costing $50 to $190, against an estimated $8,000 replacement cost for an RTX 5090.
