Chinese repair centre has received 7 melted 12+4-pin Nvidia GPUs in just the past two days alone

A Chinese repair centre reported receiving seven Nvidia graphics cards with melted power connectors in two days, bringing renewed attention to problems with the cards’ 12V-2×6 power connection. The cases matter because connector overheating can damage expensive hardware and has remained a concern for some owners of high-power Nvidia GPUs.

The repair shop, listed as North China’s Beijing Computer Repair, shared images of the damaged cards, which included RTX 5090 models. The article says the connector can overheat when it is not fully inserted or when power is unevenly distributed across its pins; the report does not establish the cause of each failure. The seven cases are a short-term report from one repair centre, rather than a measure of how often the problem occurs overall.
