RTX 5090 drew 610 W during a DLSS 5 test, melting its connector
A user named Erek said the 16-pin power connector on an Nvidia RTX 5090 graphics card melted while DLSS 5 was being tested in NBA 2K27. DLSS 5 is a technology that uses artificial intelligence to process the game's visuals. During the test, the power consumption of the MSI RTX 5090 Gaming Trio OC remained consistently above 610 W. The graphics card subsequently developed a fault and failed completely.
According to the owner, the graphics card had previously consumed approximately 450 W while gaming. After DLSS 5 was enabled, consumption increased by more than 150 W and exceeded the 575 W TDP specified for the model. TDP is a reference figure indicating how much heat a graphics card generates and the level of cooling it requires. The GPU-Z monitoring software recorded consumption above 610 W continuously rather than as a brief spike. The 16-pin connector can deliver up to 600 W of power. The PCIe x16 slot to which the graphics card is connected supplies an additional 75 W. It is therefore not possible to say that all of the recorded 610 W passed through the cable alone. After noticing a burning smell, the owner found that the cable and connector had melted and fused together. At least 5 pins on the cable had burn marks, while the plastic housing around 1 pin had melted completely. Moreover, a yellow-tipped cable indicating that it was fully inserted was used.
It is not possible to confirm that DLSS 5 specifically caused the incident. RTX 5090 connectors have melted in previous cases as well. This problem is often linked to the cable not being fully seated in the socket. Nevertheless, the owner says the graphics card had caused no problems before the new feature was tested. NBA 2K27 is currently the only game that officially supports DLSS 5. In other games, the feature is enabled through a mod.
Other tests used an MSI RTX 5090 Lightning Z graphics card with 2 16-pin connectors. The model has a BIOS with a 1,000 W limit for extreme overclocking. In Control, the graphics card consumed 800 W with DLSS 5 enabled and 691 W with the feature disabled. In a Hogwarts Legacy test, consumption rose from 480 W to 720 W. Power consumption in that game therefore increased by 50%. The RTX 5090 Founders Edition, which has a single 16-pin connector, was also tested in Hogwarts Legacy. The graphics card consumed 417 W with DLSS 5 disabled and 547 W when it was enabled. The increase for this model was 31%. The results show that the new feature significantly increases power consumption, but they do not prove what caused the connector to melt. Energy efficiency and safety remain key issues for Nvidia before the feature is added to the RTX 40 series in the future.
