12VHPWR Connector Said to be Replaced by 12V-2x6 Connector
According to Igor's Lab, who has gotten their hands on a PCI-SIG draft engineer change notice, it looks like the not entirely uncontroversial 12VHPWR connector won't be long lived. The PCI-SIG is getting ready to replace it with the 12V-2x6 connector, which will be part of the ATX 3.1 spec and the PCI Express 6.0 spec. The new connector doesn't appear to have any major physical changes though, but there have been mechanical modifications, such as the sense pins having been recessed further back, to make sure a proper contact is made before higher power outputs can be requested by the GPU. The good news is that at least in the draft spec, the 12V-2x6 connector will be backwards compatible with 12VHPWR connectors.
One of the bigger changes, at least when it comes to how much power the new connector can deliver, is that there will be new 150 and 300 Watt modes in addition to the 450 and 600 Watt modes for the sense pin detection. The 12V-2x6 connector is rated for at least 9.2 Amps per pin and the new connectors will carry a H++ logo, with th older 12VHPWR connectors getting a H+ logo. The PCI-SIG has also added stricter requirements when it comes to the cable design and quality, which should hopefully prevent some of the issues the 12VHPWR implementations have suffered from. We should find out more details once the PCI-SIG has finalised the 12V-2x6 connector specification. In the meantime, you can hit up the source link for more technical drawings and details.

Now we wait to see this getting finalized and for companies to follow the specs / guidelines to the letter and use the correct female pins (NTK) this time.

12VHPWR provides power - the 150W level - when both sense pins are open.
The rest seems to be formalizing some of the measures already being taken.
if the #2 and #3 images are correct H++ has more recessed sense pins?
Feels real premium, fiddling around with adapters no?
This definitely damages the x90's resale value, along with every other Ada card that has it. Now we have uncompromising proof Nvidia pushed this on its own, it was rushed, and its design is lackluster. That seems to become a thing for team green, quite unlike how they used to be IMHO. We tend to get features from them that actually work in general, but since RTX... pfew
But that was 'duh' to me since the moment it melted. Yes, even the odd one among many.
There's a saying, where there's smoke, there's fire ;) The world isn't complicated. We're just too naive.Same. Still not sold on this push 'forward' that really doesn't gain us jack shit except a new PSU requirement.
Also not sold on GPUs doing north of 350W. Ever
Im still in favor of an update to the PCI-E slot so it can carry all the power needed.
Keep dreaming though. Same size, inferior quality. Its fine for anything below a 4090, I would be inclined to agree. But if you run GPUs north of 300W? Definitely the current one isn't fine. If it was fine, we'd have kept 12VHPWR. Stop living in denial. In this commercial world this is the biggest confirmation of reality you will get short of them actually admitting they fucked up, which no company ever does.
It also leaves the question why people keep thinking the initial offering was good and is now not degraded. That... I can't even. Are we thát bad at reflection?Size does indeed matter, though I still have sufficient faith in humanity that we can design around that and make things more compact. We seem to manage that in many other key areas/related stuff. And then we blow the form factor up again with 4 slot coolers. :D
CableMod still uses Astron for their adapters, hence why there are melting reports on a daily basis.
Connector are more complex than just the number of pins and the size of them, the actual real physical connection is improved (you cannot securely mate two perfectly flat connector for instance, shape as a huge impact)
Also the pins have better requirements for the materials used.
This doesn't mean that 12vhpwr didn't have problem, but it's not as simple a problem as you make it look to be
