Nvidia RTX 5090s maintain melting energy connections regardless of coloured plugs
New security plugs had been purported to lastly clear up the warmth issues with Nvidia’s RTX 5090 graphics card, however latest consumer experiences present the other, studies VideoCardz.com.
On Reddit, a number of customers are as soon as once more reporting scorched energy connections, regardless that they used the yellow-colored 12V 2×6 connectors from MSI. These are literally purported to be coloured to assist be certain that the plug is absolutely inserted.
In January, Nvidia assured everybody that its new 50-series playing cards wouldn’t soften energy plugs. In February, one Reddit consumer’s RTX 5090 energy connector had melted, prompting YouTube Roman “der8auer” Hartung to research and uncover clear traces of overheating on two 12VHPWR pins underneath a microscope. His investigation revealed temperatures of as much as 150 levels Celsius, regardless of right set up.
Two more moderen circumstances have emerged
Based on latest Reddit threads, MSI safety plugs are affected. One consumer studies that the ability connector on his second RTX 5090 inside just a few weeks has burned once more. After the primary injury in July, he obtained a alternative card in August—and the identical drawback occurred once more. Based on the consumer, the GPU was even undervolted.
One other Reddit consumer describes an identical drawback: initially, his system crashed and black screens appeared till it grew to become obvious that the yellow security plug on his MSI RTX 5090 Gaming Trio was burned.
Each circumstances present that even accurately plugged-in energy adapters are not any assure in opposition to overheating and melting.
Shade marking doesn’t deal with the deeper design drawback
Based on MSI, the yellow plug suggestions are supposed to allow a easy visible examine as as to if the plug is absolutely seated. Nonetheless, as the most recent studies present, the labeling doesn’t really deal with the basis trigger, which apparently lies within the 12V 2×6 connector’s uneven energy distribution.
Whereas earlier RTX generations—such because the RTX 30 collection—distributed the ability provide throughout a number of strains, the brand new 12VHPWR and 12V 2×6 adapters route the ability via a single supply. This will result in an overload on particular person pins, which might overheat and trigger melting even when the connector is accurately seated.
These new circumstances make it clear that coloured security markings alone aren’t an sufficient answer. The basic problem continues even when every little thing is completed correctly. Up to now, Nvidia hasn’t introduced any measures to get this drawback underneath management. For now, customers ought to examine their connections frequently for indicators of warmth or discoloration.
