The NVIDIA RTX 4090 graphics card, launched in September 2022, continues to face serious issues with its power supply interface melting. NorthridgeFix, a GPU repair specialist, recently highlighted the persisting problem in a video that showcased a collection of damaged 16-pin power connectors from these cards. On average, the shop addresses malfunctions in 200 RTX 4090 units each month due to this defect. Originally, the RTX 4090 utilized a 12VHPWR connector, which has been prone to poor contact and subsequent melting. In response to the widespread issue, NVIDIA announced a transition to an improved 12V-2x6 power supply interface. Despite this upgrade, many units sold in the past two years still feature the older, problematic 12VHPWR connector.
The melting of the power connectors varies with the intensity of card usage. Some users report damage within months, while others may not notice problems for over a year. Graphics cards that are less frequently used generally show delayed onset of these melting symptoms.
