Owner Finds Frayed Cables on Dual RTX PRO 6000s
A PC owner reports heavy thermal wear on two 12V-2x6 power cables feeding a pair of RTX PRO 6000 GPUs.
Updated on Nov. 7, 2026 in Data Centers
An owner discovered frayed braided sleeving on two 12V-2x6 power cables connected to dual RTX PRO 6000 GPUs and a Seasonic PRIME TX-1600 power supply. The owner is replacing both cables after the damage was found during a physical inspection of the workstation.
Why it matters
The case points to possible current imbalance across the six 12V lines feeding high-power GPUs, a concern for anyone running similar high-wattage builds. Visible degradation at both the GPU and power supply ends shows the stress is not confined to a single connector.
The braided sleeving on two power leads behind a 600W-rated connector shows heavy thermal wear, with one cable displaying significantly more decay than the other. The inner wire insulation and plastic connector shells showed no outward damage, and the cause of the uneven current remains unconfirmed.
The players
Seasonic PRIME TX-1600 Noctua Edition
A high-wattage power supply model from Seasonic, a Taiwanese manufacturer known for premium PC power supplies, used in the affected workstation.
The details
The owner, posting as u/Doomslayer606 on the r/PcBuild subreddit, found that the braided fabric wrapping individual wires was coming apart at the terminal heads on both 12V-2x6 cables. Degradation appeared at both the GPU and power supply ends, and the owner is replacing both cables.
Timeline
The incident was published in an article dated November 7, 2026.
The Tech Race
The 12V-2x6 connector standard has drawn attention as GPU power draw climbs, and this report adds a physical example of cable wear on a dual-GPU workstation. It shows that the power delivery design is being tested in real builds beyond the lab.
Anyone running high-wattage GPUs should inspect power cables for sleeving wear and heat damage at both ends. The case shows that visible degradation can appear before any failure, making periodic checks a practical step for protecting expensive hardware.
The takeaway
Inspecting power cables at both the GPU and power supply ends can reveal heat stress before it causes failures. For high-cost GPU builds, a quick visual check of braided sleeving is a low-effort safeguard.
