Reddit user u/Doomslayer606 posted photos of their two RTX PRO 6000 Blackwell workstation GPUs showing frayed braided sleeving on the 12V‑2x6 power cables. The cards were running at 500 W, below the 600 W maximum. Commenters said the stiff, cracked sleeves are a clear sign of overheating, not normal wear. The user asked whether this is a manufacturing defect or expected heat stress.

## The facts

- Two RTX PRO 6000 GPUs were used
- Cables were operating at 500 W

## Why it matters

Workstation builders may need to replace or monitor these power cables to avoid overheating hazards.
