After the publication of the 12V-2×6 standard, the hope was great that the melting plugs of the RTX 4090 will finally be a thing of the past. Before the RTX 5090 release, Nvidia itself said that the “problems are not expected”.
This expectation dissolved in air, because several user reports quickly appeared that complain of a melted connection or melted cable on the RTX 5090. A video of the Europe tech youtuber and CEO of Thermal Grizzly Roman »Der8auer« Hartung also showed that partly 120 degrees Celsius are measured at the end of power.
The manufacturer himself has been silent since the retrospectively very unfortunate statement when it comes to the topic of the melting plugs. Instead, more and more third -party providers are working.
- So the leaker has »9550pro«Recently discovered a 180 ° adapter for the 16-pin current plug, which brings its own cooling for the plug. A small radial fan supplies the contact points with an air flow that is supposed to contain the high temperature developments.
- The plug also has a small display with which both the electricity consumption and the current temperature are displayed.
This adapter should protect you from the RTX 4090 overheating problem.
Apart from the unknownity of the manufacturer, the small plug also has the hook that the description only speaks of the RTX 4090. It is unclear whether the small device is also suitable for the RTX 5090.
After all, Chinese sources are not the only ones working on a solution: the YouTube channel Hardware Busters is also currently working on a prototype. A total of two solutions are available.
RTX 5090 adapter: Two possible solutions against the cable melt
The basic idea behind both of Hardware Busters Proposed solutions is an adapter that should randomly recognize possible overloads and, if necessary, interrupt the power supply.
The options amount to overheating protection by Cold ladder or overflow protection with Shunt resistors.
- Incidentally, the latter option is already available on the Custom market of the RTX 5090: The ASUS RTX 5090 Astral relies on six such shunt resistors, which at least trigger a software-side warning with unequal power distribution.
- However, this does not make the GPU shut down, users have to become active themselves. The Astral card also costs 2,950 dollars. In your RRP. Without taking into account the horrendous prices as a result of the poor availability of the RTX 5090, which is located on relevant portal beyond the 4,000 (!) Euros.

Back to Hardware Busters, which is also the CEO of the power supply manufacturer Cybetics. Which of the two solutions is most suitable was still open to the announcement – especially since there is also the possibility to combine both approaches. This would logically result in higher costs.
In addition, the prototype should still have some work in front of it. Hardware Busters intends to reduce the adapter. A release period and a price are still pending.
