It appears as though AMD has also fallen prey to the melting 12VHPWR connector issues that plagued the NVIDIA RTX 4000 and 5000-series cards. Although very few AMD graphics card makers used the 12VHPWR connector for the Radeon RX 7000 series, adoption rates for the new connection standard increased with the release of the RX 9070 and 9070 XT. What appears to be first recorded instance of a melted 12VHPWR connector on an AMD Radeon RX 9070 XT has been posted to the r/Radeon subreddit by a user who goes by u/Savings_Opportunity3.
The issue only seems to have affected the cable on the GPU side, and the GPU seems to have survived for now, although the user remarks that one pin on the GPU power connector is darker than the rest, suggesting it has suffered spotty contact and increased heat. The GPU is an AsRock Taichi OC AMD Radeon RX 9070 XT, although many of the commenters suggest the PSU being used in the system was to blame for the melting connector. The GPU was also connected via a 3×8-pin adaptor, not straight to an ATX 3.1 PSU, and these sorts of adaptors have also been known to result in melted connectors . There have been no widespread issues with AMD GPUs and melting connectors, seemingly due to the lower power draw, but it clearly anything is possible, depending on the circumstances.
