I didn’t expect that in 2026, we would see RTX 4090 Melting case. Recently, a foreign female live streamer played “Marvel Confrontation”gameDuring live broadcast, RTX 4090 in the computer graphics card The 16-pin power connector was burning like crazy, and she asked the audience, “Does this look bad?”

RTX 4090 reports another 16-pin smoking and melting accident: the live broadcast of “Marvel Confrontation” went viral on the Internet
According to a report by foreign media VideoCardz, a female live broadcaster jessick recently uploaded a video on her personal As you can see from the video, smoke comes out from near the RTX 4090 power connector, and the outer insulation sheath of the wire begins to melt:
Judging from the radiator casing and PCB layout, this graphics card should be the MSI GeForce RTX 4090 GAMING X TRIO model.
This graphics card is equipped with the old 12VHPWR connector specification, not the new 12V-2×6 design that NVIDIA later launched, so the white customized power cord used by the live broadcast host at that time was probably not fully plugged in.
In the past, 12VHPWR (16-pin) has been repeatedly cited as having high risks such as “incomplete insertion, bending near the connector, and poor contact” on high-power graphics cards. If a problem occurs, the temperature of the connector is likely to rise abnormally, causing the plastic shell to soften, the wire sheath to melt, and even smoke in severe cases.
Of course, not every RTX 4090 user has encountered melting. Therefore, after so many years, many users may just want to say that their RTX 4090 should be fine and not pay too much attention to this matter.
But in fact, if the power wiring is not paid special attention to whether it is connected properly, as long as it is a little loose or bent, it is likely to lead to disaster in a short time, just like the situation encountered by the foreign female live host this time.
If you are really unlucky, like this female live broadcaster, the RTX 4090 starts to melt during use, such as smelling a burning smell or seeing smoke inside the case. The first thing to remember is to turn off the power immediately.
Before re-powering on, you should also check whether the graphics card connector, cables, and power supply are scorched, deformed, or have plastic softening. If there are traces of melting, it is recommended to go directly to RMA or have it professionally repaired and inspected to avoid greater damage caused by re-energizing.
Having said that, although the RTX 50 series has been changed to a new version of 12V-2×6 design, it is not completely without melting cases.
After the launch of RTX 5090, sporadic cases have been reported one after another. The same situation is that the power cable is melted. There is even one case. Reddit user RMA’s original RTX 5090, then received a new RTX 5090 and it melted again：

It can be seen that as long as it is a high-power graphics card, it is still possible to occur, so it is recommended to use some protective accessories, such as Thermal Grizzly’s WireView Pro II, or a power supply with built-in protection mechanism, such as MSI’s GPU Safeguard / Safeguard+ technology, which will provide more peace of mind when used.
