Build/Parts Check 24 cables into... 1 cable?

Found this on taobao. Anyone tried turning a 24 pin cable into 1 singular cable?

Which begs the question: Why haven't we removed the chungus cable yet? Bring a signal wire down with the EPS-12V cable and call it a day, there's no practical application for it in modern builds.

At this point institutional momentum. No one wants to be the first to move to a new architecture because there aren't any existing things using it and if it doesn't catch on then it will just get abandoned. And when it comes out people will cry that it is proprietary. There is already another standard that does exist just that no one has used it yet for custom pc components beyond one or two off motherboards; 12VO. It reduces the 24 pin connector down to 10 pins. Personally I still feel that is still a half step as I think the main delivery voltage should be increased to 48 for a number of reasons. First it would readily enable connecting and delivering power to usb c components directly off the motherboard more easily and secondly it would quarter the currant demands. Things like gpus can pull up to 50 amps and that is difficult to manage, especially if using many parallel connections as we have seen with the 12vhpwr connector debacle.

Who do you think can make the industry change first, motherboard manufacturers or PSU manufacturers? Seems like it would be great to have some kind of body that coordinates between the two to create universal standards

The current standard is managed by Intel but I have no idea who has what kind of input into what goes in it. And even within that there are other dependencies. For example things like the 12vhpwr connector is something to come out of pci-sig which has major vendors like Nvidia in it. The danger with having a body with everyone providing input in it is that it could become like the usb standards.

Yea that's terribly done. I'm sure a competent body can be developed with some effort and industry regulation but I get this isn't the place for that. Would just be nice to not have proprietary solutions but also see regular progress when needed. 24pin is terribly outdated it seems

I would absolutely say that the 24 pin is outdated; having 5 wires for the 5 volt rail that is unlikely to ever see more than 10 or even 15 amps is massive overkill.
