Maybe the too big, hungryand high priced Nvidia’s 4000 series graphics cards are a bit too hot for a product right now. After a user posted photos of their charred 12-volt, high-power (12VHPWR) connector on Reddit, Nvidia responded with an investigation into at least two cases.

Yesterday, Reddit user reggie_gakil shared photos of a freshly singed cable and power connector on their RTX 4090 graphics card, titled “RTX 4090 Adapter burned” with a caption that reads “IDK [how] it happened, but it stank and I saw smoke.” While the map is reportedly still working, reggie_gakil wasn’t alone. Another Reddit user started his response with, “You’re not alone. That happened to me today.” This follows reports that PCI-SIG, the consortium that sets standards for PCI, PCI-X and PCI-Express connections (the ones used in said graphics cards), was aware of potential “security issues under certain circumstances”. According to The edgeNvidia is now investigating these cases.

In a statement to KotakuNvidia said it is “in contact with the first owner and will contact the others for additional information.”

With the increased power consumption of these new graphics cards and new ATX power standards that have raised eyebrows, this may not come as much of a surprise. Indeed, YouTube channels like JayzTwoCents are doing a bit of an “I told you so” victory round.

The 12VHPWR cable is DANGEROUS! But NVIDIA disagrees…

As mentioned in the video from JayzTwoCents, Brandon Bell, senior technical marketing manager for Geforce at Nvidia, dismissed early fears about unsafe power cables as “problems that don’t exist” and that “it all just works, man.” While the results of Nvidia’s investigation have yet to determine whether the first Reddit post that raised the alarm is an outlier, there is certainly cause for concern.

Nvidia’s competitor, AMD, also responded to reggie_gakill’s melted cable story. AMD Radeon’s Senior Vice President responded to a Tweet continue that “the Radeon RX 6000 series and upcoming RDNA 3 will not use GPUs” [the 12VHPWR] link.”
