Given that its launch, the RTX 4090 has actually presented a brand name brand-new issue for PC hardware lovers or specialists choosing to stuff as much visual horse power as possible into their rigs. With a lot power, the 4090 needed a more effective adapter, however it has one deadly defect: It likes to melt. Concerns that started years earlier on the 4090 are still taking place now, as the RTX 5090– together with the RTX 50 series, which utilizes the very same port– has actually had its reasonable share of melting occurrences, too.
The multi-trillion-dollar AI hardware business Nvidia has relatively still not resolved the issue, in spite of having currently fixed the issue ahead of time. As explained by Hackadaythe RTX 3090 Ti, Nvidia’s updated variation of its flagship card from the generation before the 4090, is developed so that the power is stabilized over a three-phase circulation. This permitted the 450-watt gadget to track any possible damage that may be coming through the pipelines. The up-to-600-watt RTX 4090 and 5090 do not include anything of the sort– the 5090 does have shunt resistors to determine the present, however once again, absolutely nothing to stabilize it.
Concerns emerge with the adapter, the 12VHPWR and 12V-2×6, since a fault in the balancing of the current can melt the port. 12V-2×6 is the upgraded requirement for the 5090, with 12VHPWR being discovered on the 4090. In a Hardware Unboxed videothe YouTube channel discovered that the brand-new adapter on the RTX 5090, ranked at 600 W, was piping all the power through simply 2 of the cable televisions on the port. It melted the adapter throughout additional screening.
It appears there’s no genuine repair for melting Nvidia cable televisions
MSI has actually presented yellow-tipped cable televisions to provide an indicator of when the cable television is completely linked. Faults with the cable television or GPU itself can still trigger melting. Zotac included a security light that would inform the user when it is completely placed. Galax took it an action even more and presented RTX 50-series cards with RGB lights baked into the card’s shell to suggest when it is effectively powered.
It appears not likely that we will see Nvidia tackle this issue whenever quickly. Even on its RTX Pro 6000 cards, some cable televisions are still melting. Regardless of its tradition in gaming-centric and consumer-facing hardware, Nvidia is now all in on the AI market. Unlike every year for almost the last years, Nvidia has actually not introduced brand-new consumer-dedicated cards, with an RTX 50 Ti series or RTX 60 series missing out on from its CES statements in January 2026. It did launch RTX Spark chips, and of course, a lot of brand-new and pricey AI hardware for information.
