Another User Sees Melting Of 16-Pin Connector On The PSU Side, But This Time With NVIDIA’s RTX 5080 – Wccftech
A Reddit user posted pictures of a melted 16-pin power connector on his PSU, but the system was running an NVIDIA GeForce RTX 5080 this time.This is perhaps the first time we have seen a melting 16-pin connector in a system containing the NVIDIA GeForce RTX 5080. Two days ago, we reported a case affecting a user’s RTX 5090 GPU, in which both the GPU and cable connectors melted due to overheating. While this wasn’t a big surprise, considering how power-hungry the RTX 5090 is, the RTX 5080’s case is shocking.A user who goes by the username r/Ambitious_Ladder1320, posted on the ASUS sub-Reddit that he faced a similar melting issue with this setup, which consisted of the RTX 5080 and an ASUS ROG Loki PSU. He states that the GPU was flashing a red light, indicating improper seating of a pin on his connector. While the user states that he did connect the connectors properly, he still tried once again after turning off his PC.While this time the error didn’t reappear, the monitor resolution and refresh rate were automatically downgraded. Moreover, the GPU started to run in PCI-E x3 mode, which is a weird behavior.Once again, after replugging all the cables, the user came across the melted 16-pin connector on the PSU. Thankfully, the GPU didn’t face such a problem.The user says that he has seen three similar incidents with users owning ROG Loki PSUs, but it isn’t clear whether those users were using a 12VHPWR connector or whether they were running an NVIDIA GeForce RTX 5090 or an RTX 5080 GPU too.Nonetheless, the ROG Loki PSU is the same model that was seen in the RTX 5090’s melted connector case. However, as Der8auer showed in his demonstration, the melting was caused due to overheating of the connectors as two of the wires were carrying significantly higher load than they were designed to.There have been lots of talks going on the social media concerning the 12VHPWR design and the quality of wires, and the connector is likely the culprit here as well. Both ends of the cable generally overheat due to having little to no headroom for supporting higher power. This results in quick melting of the cables and the connectors on either side.Whatever the root cause is, the issue is now becoming more common despite the RTX 5090 and RTX 5080 not being widely available. However, we have yet to come across problems with a 12V-2×6 connector, which is the upgraded 16-pin connector one should use with these GPUs.News Source: RedditSome posts on wccftech.com may contain affiliate links.
