I've been saying this for a while now, but the ATX standard needs a complete modern redesign centered around the GPU, instead of the CPU like in the 90's, when that component was the most important and energy intensive one.
But since Intel is the original designer and contribuitor of the ATX standard, I doubt they're looking forward to give up the throne in the system to Nvidia/AMD till they gain any majority share in the GPU market which won't happen in my lifetime.
The ATX standard is far too long in the tooth already and you can see various people doing their own hack jobs at home, while case and motherboard manufacturers try to innovate around it without Intel, going in their own directions with non-standard deviations and hacks, meaning components are expensive due to lack of economies of scale and cross-compatibility is a mess.
I guess the lack of interest in modernizing the ATX standard also stems form the fact that PC sales have been on the decline for over a decade(pandemic excluded) due to the rise of mobile use, with tower PCs seeing an even bigger decline as most people and companies who still need PCs use laptops now, meaning ATX style PCs have made a 360 turn back to being a rarity for hackers/geeks/gamers instead of something everyone had to have in their homes and offices.
But what I personally want today is not another quirky square box occupying space on my desk/floor, but a stealth desk PC like this one (watch the video it's worth it): https://www.youtube.com/watch?v=UQ6ueTe8KQM
If ATX is being redesigned today, than it will not become better but worse for end users. Things like moving major power supply to the motherboard - for instance like in the 12VHPo standard.
Not to mention that most of the power provided by modern PSUs come from the 12V rails. The 3.3 and 5V rails are almost vestigial at this point, no hardware actually runs directly at those voltages, so removing them would not have any negative effect.
Because it moves complex circuity to an already very complex and expensive PCB, making it even more expensive. A power supply is likely to outlast multiple (re)builds of a desktop computer; a motherboard is likely not - especially not Intel motherboards.
I worked on 1 or 2 boxes designed like that, and they were just annoying. Instead or a "redesign" that I agree with you we need; Simply described, it's an upside down ATX.
OH yeah I remember BTX, but that design was dated even for that time since it was only meant to stop Pentium 4s from overheating, not accommodate the monster GPUs of today. It was clever that it would Cool the PSU and CPU with one fan but it was still overall crap.
Also, just because a poor replacement suggestion failed once in the past, doesn't eman it's an excuse to give up on replacing ATX with something better.
