Just got my hands on a 4090 FE, and I've been looking at cablemod's offerings. After reading some of the comments here I'm a little apprehensive about ordering, I hope things are working out for your setup so far!
Be careful though when plugging this cable in. A plastic anti-bend shield moves down towards 12VHPWR plug when you apply force to plug the cennector all the way into a GPU. It could give you an illusion that it is all the way in but it won' t be. This is a main reason that cables are melting, not plugged all the way in. Very poor decision from Cablemod to add a clip-on plastic to the cable. They are preventing "a bend" and promoting "a poor plug in" that is possibly the acctual reason for melting cables.
How is your Cablemode cable working right now? Is it doing good? No issues so far? I would love to know as I just recently bought a TUF 4090, didnt like the ugly adapter that comes with it as I cannot close the side panel with it, so decided to get the Cablemode 4 x 8 Pin for Corsair. Hope this will work out fine.
Straight cables from Card to PSU also claimed to be melting. I'd put a thermocouple & monitor the temps of the connector for a good while before considering the setup safe. If it does melt that has to be due to a gradual rise in temps and then past the melting point of the plastic used to mfg the connector. It can't be a sudden spike as that will certainly result in OCP kicking in and shutting the PSU down. This has to be a gradual build up that it's too late to notice because there is no means to warn/prepare yourself for it until you smell burnt plastic.
"Like other testers, Johnny Guru intentionally tried to get an adapter to melt and was unsuccessful. Even when he broke one of the outside power leads completely off, the adapter never melted. Also, the probe he used never reported temps higher than 53C. This lead him to reexamine the photos people posted online of melted adapters, and he came to a simple conclusion: People aren’t plugging them in all the way (above). He notes this is not necessarily their fault, because the new adapter is apparently difficult to insert fully. This is due to the new sideband rails that communicate with the GPU, he says. He also notes we’re seeing more melted adapters versus ATX 3.0 cables just because the former are more prevalent." "the adapters are actually fine. They are just very difficult (emphasis his) to insert fully. Overall, it does seem like there is sufficient solder, and the connection is very solid. Even if it’s bent, or damaged, nobody has been able to force it to melt so far. Still, more testing is required before this can be confirmed. A word from Nvidia would certainly help too, but we’re still waiting on that. For now, if you have an RTX 4090, make sure you can’t easily unplug it once it’s inserted. If you can just pull it out, it’s not fully seated." CORSAIR
@@kenmasters916 yeah the issue is MASSIVELY overblown by garbage youtubers for clicks. Did it hapoens once ? Yes, does it happen easily ? Nope, even when trying really hard nobody can replicate it at will. It’s really really cringe.
@@kenmasters916 That all doesn't negate the fact that there is indeed something happening and so the engineering teams have to try everything possible to replicate and then repeat what they find as a possible culprit to prove it is repeatable. Then, and ONLY then, a solution can be found. Right now many people have various expert opinions, Jonny guru's is just another opinion, he couldn't find the problem but yet there is a problem. I am all for investigations but it never helps when people just make up something and claim this could be the issue when clearly they couldn't even replicate the issue. This is not to disparage these people but rather to highlight the common tendency of many to dismiss something as just a case of vocal minority voicing issues. Pretty much like when the most successful products have RMAs to process, there can never be a 100% flawless product. However, here we are way past the threshold of RMA style returns, stuff is actually melting, this is not proper. There is an engineering problem at hand that needs to be solved.
@@mclarenbutton6342 "teams have to try everything possible to replicate and then repeat what they find as a possible culprit to prove it is repeatable. Then, and ONLY then, a solution can be found." No, you mean then and only then we can claim there is an actual connector/hardware issue and not user based, you had it backwards. But thanks for sharing your opinion. What are your credentials ? Im sorry, but I think Ill take Corsair’s PSU Chiefs word over yours. No offense. But hes completely contradicting everything you just claimed. And, lets not forget, not 1 single credible source has been able to duplicate the issue. That kinda defeats your entire opinion tbh.
Got my cable today and I would say this. Just be careful with this cable, item has been shipped from China and I do not believe proper QC has followed. Insinde the cable combe there are 2 thin cables which are responsible for letting card know about the power etc. As those are exposed rather than hidden inside the wire, might be easy to break them or bend them. My one arrived bent to the point where you can see it's broken so I would suggest inspecting your cables before plugging them in to your rtx 4090.
You be behind on the news, those splitter cables use cheap solder joints, and bending the cable breaks the weak joints. Edit: actually scratch that, you mentioned the videos, so you have to already know.
Yeah, I wasn't going to go to deep as there is a lot of speculation. However Nvidia apparently is now saying there are two manufacturers of the connectors and one may not be made as well
Hello, ModFlex is softer, more flexible sleeving option. ModMesh is stiffer, more vibrant sleeving option, which is also UV reactive, as well as a more durable sleeving type
My cable comes this week...but I have all braided EVGA G2 1300w carbon cables and that was sold out. I ordered the same black on in this video so that will have to do. I'm more worried about putting the waterblock on.
@@BlueprintPC MSI Gaming Trio...was going to go with EK water block but went with the Phanteks Glacier G4090 block. I will only say this - Get the Phanteks water block! It is better than EK and thicker...but get your own 1.5mm thermal pads instead of using the included pads. This goes for any 4090 block. I got the Kritical pads and they are leagues better than the crappy stock pads.
@@BlueprintPC I'm bench testing everything today to make sure everything is fully operational...then I'll start putting the system together. I just took delivery of the acrylic tubes yesterday. Only part left is nvme drive
One of the clues being overlooked generally on this topic across multiple videos and sites is that many of these failures happen after 3 weeks, or several months, or 9 months etc. So think about that for a minute. We're shoving 300 to 400 W across one to three tight pins on a new design connector and getting a run away heat accumulation. But it doesn't happen right away but fails after a significant amount of time. Why ? What could cause this ? I submit, Corrosion ! ... namely oxidation at the exact fine point of pin contact. We know that oxidation increases with heat exposure and air exposure over time ... and that corrosion causes even more heat due to resistance and before you know it you have a run away heat buildup. So, how do we prevent this ? and I am amazed at how little attention this idea gets ... like with any electrical contact surface which carries a high load with respect to surface area, we have to protect the existing 'ok, but not great' connection with an anti oxidation contact grease designed for this purpose. Yes, they do make them, they are lithium based and in this case we want something that encourages conductivity not discourages it , so we don't want a 'dielectric no-ox' ... so get 'dielectric grease' out of your head cause that's what comes to mind with most people ... we want the opposite of that. Craig labs makes the perfect solution for this, its called DeoxIT L260Cp ... the 'Cp' stands for copper particles ... it has copper particles in the grease, it's lithium based so it will not degrade under heat stress. I'll be applying mine with a needle type applicator ... sparingly ... inside the barrels of the connector.
