When the NVIDIA GeForce RTX 40 series debuted back in 2022, the issue surrounding melting power cables and connectors, particularly on the beastly GeForce RTX 4090 created doubts about GPUs going forward with ever-increasing TDP. Despite 2024 had less news about busted high-end GPUs due to “cables not being connected properly” or “positioned at the right angle”, it was not until the 12VHPWR was replaced with the revised 12V-2×6 solved the problem at scale.
However, the new Blackwell-based GeForce RTX 50 series consumes even more power as expected with the official TDP of the RTX 5090 placed at 575W (125W higher than 4090 by the way) which caused a small rouse about 12V-2×6’s ability to handle such power draw. But thankfully, NVIDIA Korea’s Technical Marketing Director, Sunwook Kim, came and expressed confidence, stating:
“We do not expect that to happen with the RTX 50 series. We made some changes to the power connector to respond to the issue at the time, and we know that it is not happening now, about two years later.”
The 12V-2×6 features recessed sense pins and longer power pins that can help ensure fully inserted cables and only power up the whole thing when everything is detected to be “good to go”. With the GeForce RTX 50 series continuing the trend of using this connector, we do encourage users to double-check their builds in terms of cables and connections or seek professional help from local DIY PC shops if they’re not familiar with the ordeal.
