The braid is fraying at both ends
Posting as Doomslayer606 on Reddit’s PcBuild forum, the owner says the workstation uses a 1,600 W Seasonic PRIME TX-1600 Noctua Edition. He spotted frayed fibres just behind the 12V-2×6 connectors. Both cables are reportedly affected at the graphics card and PSU ends, with much more pronounced damage on one cable.
His most telling observation concerns what lies beneath the braid. The textile covering on some wires is coming loose and feels stiff or cracked in places. The electrical insulation underneath appears intact to him, and he sees no discolouration or melting on the connectors. The original photos show the outer covering. They cannot establish the temperature reached or the cause of the damage. The gallery at the end brings together Doomslayer606’s five photos: two views of the cable bundle and three close-ups of the plug and the sockets on the graphics card and PSU.
“The actual wire insulation underneath appears intact, and neither the GPU nor PSU connectors show any visible melting or discoloration.” — Doomslayer606
What the manufacturer recommends
The owner says he will replace both cables. NVIDIA rates the RTX PRO 6000 Blackwell Workstation Edition for up to 600 W of graphics power. That specification does not tell us how much power the cards in this workstation actually drew.
For this connector, Seasonic says the latch must engage fully and advises against bending the cable right next to the plug or putting it under tension. If a cable shows similar damage, stop using it and ask the manufacturer for a replacement part compatible with the PSU.
Which replacement cable should you use?
Seasonic publishes a compatibility table by PSU family and cable type. Match the exact PSU and modular cable part numbers. The “600 W” marking on the graphics card plug does not identify the PSU-side pinout. The manufacturer’s diagram illustrates the clearance to leave near the plug. It cannot diagnose the damage in these photos.
Key takeaways
So far this is one owner’s documented report. It does not establish a widespread fault. Neither GPU was reported lost, and there is no evidence that a connector was about to melt.
