12VHPWR Connector Said to be Replaced by 12V-2x6 Connector

[TheLostSwede]

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.

All those beta testers who spent their hard earned money on $1600+ GPUs are going to feel the pain over this update.

How? It’s backwards compatible.

Wonderful !!

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.

Another noteworthy change lacking in the article is that the sense pins are further recessed in the pin chamber, requiring a tighter connection before power can be delivered.

Good spot, added that.

Ok, I was going to upgrade to a high end PSU, with that said, I am going with a 80 Plus Gold, and then wait to see what might happen. Thanks for the sharing.

 

[Jism]

I'd still take even up to three 8 pin all day and night.

Didn't paint yellow on the connector ? FAILED

That's not going to help if the connector has the ASTRON female pins in it, they are not fit for purpose, they need to use the NTK female pins when you have GPU's that can pull over 300 watts.

The major change seems to be sense pins. Recessed sense pins along with 150W being shorted pins instead of both Open will somewhat better ensure that connector is inserted before any power can be provided.
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.

Anyone know what the difference between the H+ and H++ designs is?

if the #2 and #3 images are correct H++ has more recessed sense pins?

Just updated the articles to explain the difference. H+ is the current and H++ is the new connector.

Because Nvidia ripped you a new one. Literally. And it has no future lifecycle.

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

 

[ZoneDymo]

pretty amazing stuff, how hard is it to develop a plug....hard apparently.

Im still in favor of an update to the PCI-E slot so it can carry all the power needed.

Yes that makes sense. Thank you.

It's the same size as the old one, maybe read the arictle next time.

 

[Vayra86]

No?

It's the same size as the current one.

"to make sure a proper contact is made before higher power outputs can be requested by the GPU"

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.

CableMod still uses Astrom for their cables and adapters, it's no doubt the cause as to why there are melted connector reports daily on their reddit.

It's the same size connector, just different length sense pins. This update will not fix 4090 melting.

I think it does, because it won't deliver the 450W/600W unless properly seated.

There is fundamental problem with the 12/16/2x6 pin connector

Or, here's another wild idea: maybe this is how the industry has always worked. Someone builds something for the first time and then, based on the first implementation(s), we iron out the kinks and develop a standard.

Hear, hear!

Sure it has always worked like that, still that leaves even MORE questions on why Nvidia pushed this with the shit adapter they themselves offered with their top end product.
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.

It should start by banning the Astron 3-dimple terminals. NTK 4-spring should be the norm.

CableMod still uses Astron for their adapters, hence why there are melting reports on a daily basis.

The CPU 8pin connector can do 400W in certain cases, it has been used on server gpu, were you see only one of those cpu connector at the end of the gpu, and there's absolutly no problem with this

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
