Recently, the 16-pin power interface of NVIDIA’s next-generation RTX 4090 graphics card was burned out, which caused a lot of discussion among netizens.
According to the latest foreign media reports, the PCI-SIG organization is considering retrofitting and strengthening the 16-pin 12VHPWR interface, but is still under research and plans to complete the overhaul by December 6. According to the leaked documents, PCI-SIG has designed two new bracing schemes, mainly around the separate 4-pin signal line, adding more protection and support around the socket and plug to make the connection more stable. However, the remaining 12-pin lines are completely unchanged, that is, if there is excessively high current, there is still a risk of burnout.
Corsair power expert Jon Gerow points out that burnout can be as simple as not plugging in tightly, leaving a gap between the plug and socket. As you can see in these two images, the first is completely disconnected and the plug is also visible from the outside, while the second is correctly inserted and completely inserted. However, some netizens soon questioned themselves, saying their connectors were connected too tightly and still burned.
