The 12VHPWR connector has struck again, this time affecting a budget graphics card—the GeForce RTX 3060 Ti. Known for consuming just 200-250W, this card unexpectedly experienced a dramatic issue.
An ASUS GeForce RTX 3060 Ti ATX/Megalodon, featuring a 12-pin adapter cable, suffered severe connector melting. While usually seen in high-end cards like the RTX 4090, this kind of damage is rare in mid-range ones. Released in 2023 for the Chinese market, this GPU surprisingly came fitted with a 16-pin power connector.
The key issue lies in the unusual adapter provided with the GPU—a 12-pin to dual 8-pin PCIe connector. This is for users whose Power Supply Units (PSUs) lack a native 16-pin connector. Unfortunately, the adapter omitted four critical sense pins, which are essential for ensuring a secure connection. Without them, there’s no guarantee that the GPU receives power properly.
The absence of these pins likely led to the catastrophic melting witnessed in the images. Although the 12VHPWR connector can safely handle 200-300W, issues arise when power exceeds 400W. The RTX 3060 Ti in question has a limit of 310W, and a slightly loose connection would make such an incident almost inevitable.
This appears to be the first known instance of a melting connector on an RTX 3060 Ti. While some blame might be placed on the user for utilizing the adapter, ASUS also holds responsibility for providing such a flawed component.
