Comparison of 16-pin to 4 x 8-pin and 16-pin to 2 x 8-pin PCI-e cables.
Comparison of 16-pin to 4 x 8-pin and 16-pin to 2 x 8-pin PCI-e cables.
I'm trying to grasp the distinction between these 12VHPWR cables. I've heard that the 16-pin to 4 x 8-pin PCI-e cable is superior, but I'm not sure why. Could you clarify? Is it more reliable and less prone to failure? I'm curious because my ASUS ROG Thor P2 1000w PSU came with a 16-pin to 2 x 8-pin cable, while CableMod has a different version.
The adapter included with the Thor P2 works adequately. Most power supplies featuring four 8-pin PCIe connectors will only use two cable strands, meaning the total power flow remains consistent regardless of the number of cables.
Follow the best guidance and avoid getting involved in all the Reddit discussions.
If you employ an adapter, ensure there are no sharp bends close to the plug, maintaining a minimum of 35mm distance.
When inserting the cable, gently grasp the wires with one hand while firmly pushing the plug in straight with the other. This prevents the pins from loosening.
Refrain from using cablemods, as it is clearly mentioned that third-party adapters will cancel your warranty.
It isn't. If it were, then every adapter sold alongside and with each power supply would cancel the warranty, causing a major industry backlash with no one wanting to meet the required specs, which isn't happening. Seasonic, Corsair, Silverstone, and others placing adapters in their boxes with current power supplies are third-party when it comes to adapters, just like Cablemod. Plus, most major tech companies have backed the Cablemod adapter, something they wouldn't do if Nvidia or its partners had raised concerns about warranty voids. Tom's was incorrect. Cablemod has clarified.
This particular location, though not a reliable reference, stands out as more trustworthy than an ordinary Reddit thread. CableMods 90 adapter, which they are now delaying And Seasonic, essentially just a cable with a 90° plug
Thank you for your reply. I was familiar with the thread you shared, but upon reviewing the ASUS warranty details, it clearly lists this as an exclusion: "damage from parts not manufactured or sold by ASUSTeK" (source: https://rog.asus.com/us/supportonly/rog-..._warranty/).
Given this, I believe the situation is a balance—using a cable that might fail but keeps the warranty intact, versus a higher-quality cable that could work better and is covered. Right now, I’m considering sticking with the ASUS cable.
Businesses aren't allowed to simply cancel warranties because they've integrated other components with theirs. That's covered by the Magnussun-Moss warranty rules. If they could do that, then every power supply maker could void your warranty for using another manufacturer's graphics card or custom-sleeved cables.
Of course, if a company can demonstrate that their product failed due to a third-party component, they might refuse coverage under warranty—but this applies only to items you can legally purchase. For example, if a refrigerator stops working after being plugged into a wall socket and the failure is traced to the outlet, they won't replace it. But trying to prove such issues is expensive and time-consuming for them, so they often choose not to act.
It doesn't matter what Nvidia claims; they must follow the law just like everyone else. It would be unfair to expect them to limit you to only their faulty adapters, just as car companies can't restrict tires to their own brands. So, regardless of the situation, anyone who believes Nvidia has the authority to dictate acceptable adapters is misunderstanding the regulations. For other countries with stricter consumer protections, like Australia, the rules are even more clear.
It's likely that companies such as Seasonic, Corsair, and Silverstone will soon challenge Nvidia on this matter, especially if they don't quickly replace the faulty, low-quality parts. They stand to lose their relationships with major power supply manufacturers, which could seriously impact their business.
I believe we have a clear understanding of the warranty terms. I wouldn't rely on the Nvidia adapters, but I would opt for the one that came with the ASUS ROG Thor P2. It seems unnecessary for ASUS to investigate whether a melted CableMod cable affected the graphics card. Although the Cablemod cable appears higher quality, there remains considerable uncertainty regarding the melted cable issue. Just yesterday, someone with an ATX 3.0 PSU shared their experience with the melted cable. It might be related to the new 12-pin cables. Therefore, I prefer using the ASUS ROG Thor P2 12 pin cable for added confidence, as their warranty covers damage caused by ASUS components only.
It's straightforward to identify the reason behind the melted cables. It has already been established. There is no doubt that inadequate construction quality, paired with stress from an angled installation, is the root cause.
This method for handling the 12VHPWR is executed correctly: using crimping rather than soldering and ensuring proper power delivery to the GeForce RTX 4090 | igor´sLAB
Initially there were bent cables, followed by dissatisfied buyers of the expensive NVIDIA GeForce RTX 4090, regardless of model or brand. The maker of the 4-pin adapter from 12VHPWR…
If Tom's claims about Nvidia voiding warranties are accurate, would that imply all Gainward 4090 customers also lose their warranty? I'm not sure.
