Ever since we reported the primary case of an NVIDIA 16-pin connector melting on the GeForce RTX 4090 graphics card, there have been numerous discoveries. Now a number of days after the problems have been first reported, it appears like GamersNexus and Igor’s Lab have lastly bought to the underside of the problem.
NVIDIA GeForce RTX 4090’s Adapter Is To Blame, But Not All of Them! 300V 14AWG Cable Runs Perfectly Well, 150V Leads To Melting
While NVIDIA and its AIB companions are working to resolve the 16-pin connector points, the PC tech group is tough at work to search out out the actual reason for the problem. In the earlier report, we bought to know that it was positively the adapter that was answerable for the melting and never the cardboard or the plug on the cardboard itself. The 16-pin connector bought actually sizzling when correct contact was not made or if the cable was bent an excessive amount of. This led to an extreme quantity of present passing via the cable which additional led to increased temperatures and the resultant melting occurred.
Steve Burke at GamersNexus has now found that whereas the cables themselves are the problem, it’s not all cables that may result in the burning or melting of the cardboard. The tech outlet noticed that every one of their cables have been labeled as “300V 14AWG” whereas those that have been proven by Igor’s have been rated at 150V. That’s an unlimited distinction. But not simply that, there was additionally a distinction within the solder between the 2 cables.
NVIDIA 16-Pin 300V Adapter Cable (Known Good Cable):
Since each shops ripped the connector off, it was came upon that the 300V cables use high-quality soldering whereas, on the 150V, every cable line is soldered individually & with a smaller soldering floor that may result in injury whereas bending. This should clarify why the cable in Igor’s case got here out unfastened. The cable utilized by Steve (GamersNexus) and Ronaldo (TecLab) was ready to withstand torture via numerous endurance and sturdiness checks. Both GamersNexus and TecLab additionally ran the cable for hours below load.
NVIDIA 16-Pin 150V Adapter Cable (Bad Soldering through Igor’s Lab):
In GamersNexus’s case, their NVIDIA GeForce RTX 4090 graphics playing cards have been run for over 48 hours below load whereas TecLab had their 16-pin adapter cable working below a load tester with a 1530W sustained load. So this leads us to the conclusion that there are simply unhealthy cables which can be inflicting the problem however why they’re there within the first place is one thing that solely NVIDIA and its AIBs have the reply of.

There’s no method of figuring out which cable you get until you pull off the sleeve a bit. In the case that you simply did get a 150V 16-pin cable, you’ll be able to ask the producer for a alternative with the correct 300V cable. The good factor is that there aren’t a lot of customers who acquired the 150V 16-pin cable. NVIDIA’s GeForce RTX 4090 graphics card is now with 1000’s of avid gamers and whereas there are lower than 20 studies of the cardboard melting up, they’re nonetheless sufficient to be a priority. Based on surveys carried out by HardwareLuxx and GamersNexus, it appears just like the variety of customers who bought the 150V adapter is below 7%.
Since we now have fairly a lot of patrons of the GeForce RTX 4090 in our discussion board @hardwareluxx_de, I requested the query which adapter comes with the cardboard. 3x 8-pin 150/300 V or 4x 8-pin 150/300 v. So far the outcome appears like this. So there are some 150 V rated circulating. pic.twitter.com/BiWdDSbuD2

Just holding everybody up to date: Out of about 130 emails up to now to the 4090cable inbox, we have acquired 7 which can be 150V rated wires (and subsequently probably indicative of various provide), so 5%. That score does not immediately imply it is unhealthy. Replying to some for information

GamersNexus additionally advises that house owners of the NVIDIA GeForce RTX 4090’s 16-pin adapter cable use the next directions to verify what cable model they bought with their card:
So the overwhelming majority of avid gamers who’ve the 300V adapters should not fear an excessive amount of however it’s nonetheless suggested to verify your cable to see if it is positively the great one or not. We already checked 7 of the cables that got here with our samples (FE, SUPRIM X, SUPRIM Liquid, Vulcan X, TUF Gaming, AORUS Master, SG) & all of them are rated at 300V. You may also inform us within the feedback under what cable you bought along with your NVIDIA GeForce RTX 4090 (FE or AIB) card in case you personal one.
