The 12-pin power cables keep melting due to their design flaw and, in this particular case, both sides of the cable were affected.Another Case Of Melted 12-Pin Connector Emerges: Connectors On Both RTX 5090 And PSU MeltedIt appears that the melting 12-pin connector issues won't stop appearing any time soon. This is something that apparently cannot be solved unless the very flaw in the 12-pin connector design is fixed. Unfortunately, the issue is mostly prevalent on higher-end RTX 50 cards, particularly the RTX 5090, which can consume nearly 600W at peak load.One such case emerged recently where the user saw the melting of the 12-pin connectors on both the PSU and GPU. It's mostly seen on the PSU side but isn't limited to it. This time it affected both the GPU and power supply, permanently damaging the components. The Reddit user u/Roachard posted pics of the melted connectors on his cable and PSU.Image Credit: reddit.comAs per the user, the overclocking wasn't enabled and the cable used was 12VHPWR, which came with the power supply. It was the Corsair SF1000L, a premium SFX power supply that was used to power the MSI RTX 5090 Gaming TRIO OC. As usual, there were a few wires that resulted in the melting of the connectors. If you take a close look, you will see around four pins on the connector that were affected notably, even though other pins were affected as well, but not to a great extent.Image Credit: reddit.comOne pin shows a bulge due to plastic melting and the pins on the other end were melted horrifically. In some previous cases, we saw similar occurring where one or two wires of the cable were carrying the entire load. This is something that happens when the connector isn't properly connected and the entire load shifts to the pins that make full contact.In some cases, the temperature exceeds 150 degrees Celcius, which is enough to melt the wires and the connector. As far as this case goes, the user spent nearly $2900 on the RTX 5090 card, which is something most users wouldn't be able to spend on a GPU. Even though the card or PSU could be replaced through RMA, the issue will likely be replicated.Surely, there are fewer chances of such incidents happening with the latest 12V-2x6 connector, but what it essentially does is allow you to ensure proper contact, but it doesn't eliminate the design flaw that lets the cable carry the entire power through a few wires.News Source: RedditDeal of the Day
