A Reddit user posted photos showing stiff, cracked and peeling braided sleeving on the 12V-2x6 power cables of two Nvidia RTX PRO 6000 Blackwell Workstation GPUs, asking whether it was normal wear or overheating. The GPUs were capped at 500W, under the 600W maximum, yet commenters concluded the damage pattern pointed to heat buildup rather than manufacturing defects. The user said lowering power further to 300W wasn't viable since it would cut performance by up to 50%, jeopardizing work deadlines.

A Tom's Hardware reader, Anthony DeMarco, says the 12V-2x6 power connector on his $5,245 Digital Storm Corsa prebuilt melted weeks after he began using it, despite the PC having sat boxed and unused for roughly a year after purchase. The system, built around an Nvidia RTX 5090 and a 1,000-watt Digital Storm power supply, reportedly suffered the worst damage at the PSU itself, with cables fused into the connector.

Thermal Grizzly has partnered with Noctua to launch a Noctua Edition of its WireView Pro II, a device that monitors current on individual 12V-2x6 connector pins to catch dangerous imbalances before they damage GPUs. The new version swaps in a Noctua NF-A4x10 fan, redesigned grille and larger CNC-machined aluminum housing to cut fan noise, running semi-passively and staying silent even under a 300W load in warm conditions.

Tom's Hardware reviewed the Phanteks AMP GH 750W, a Helly Technology-built power supply that replaces the Seasonic-based AMP line. The unit delivers strong 12V voltage regulation, low ripple, Japanese capacitors and an 8-year warranty, but its 12V-2x6 connector is limited to 450W of output. Despite that restriction, the reviewer calls it one of the better mainstream 750W options given street prices under $90.
