ATX 3.0 standard 16-pin 12VHPWR connector: is AMD and/or Intel going to adopt it?

[Solaris17]

It's a connector which only Nvidia cards currently use and Nvidia was also one of the companies (alongside Dell) behind the standard itself.

For all intents and purposes it's their connector and their problem, I don't know who else would be responsible for it. I mean if you're behind the design of a connector which is prone to user error is it not an issue you need to rectify it ?

Oof that’s a shame. I thought you were one of the ones capable of complex and critical thought but with bias that strong it isn’t worth the time.

You can find those answers and misgivings in the previous threads about the cables. I think it’s important for everyone to educate yourselves on the origin and manufacture of the cable and catchup atleast on the revision being pushed, that’s all ontop as RTB so correctly put it “tempest in a teacup”.

As for adoption by the other manufacturers? Yes I think it will happen for sure.

Like candles to the lightbulb there will be those that oppose it but it’s just users, they are free to use whatever adapter they wish in the GPUs they make in their basement.

As far as I know there was nothing overtly wrong with the manufacturing of the cables, unless you know something I don't. Manufacturers build the connectors according to a specification, a specification devised by Nvidia. Explain to me again how it's not their fault if by design they are prone to user error, you call me biased but I really don't understand why is it so hard to admit they messed up on this one.

The revision being pushed is supposed to fix this problem but you can't just deny that the problem never existed to begin with and that it had nothing to do with Nvidia, of course it did. And by the way that revision is actually from Intel not Nvidia. Strange that Intel felt that was necessary but Nvidia didn't, it's almost as if they are avoiding responsibility for something they made and expect the rest of the industry to fix their mess.

I get that some of you are strangely comfortable with the thought of video cards of a certain brand melting in your PC but I'd rather see AMD and Intel stay out of this if possible.

Not sure why they even changed the cable design, a case of fixing something that isnt broken. Maybe thats why so far only Nvidia has adopted it.

"12VHPWR is a type of 12+4-pin power connector, used with the brand-new ATX 3.0 power supplies.

A 12VHPWR connector has been designed utilising premium quality materials to deliver up to 600W of power, all from one singular cable. The combination of 12- and 4-pins will not only supply plenty of power to your graphics card but also allow your GPU and PSU to communicate more effectively.
These cables have been built specifically for the latest power-hungry PCIe 5.0 NVIDIA RTX 40 Series GPUs and ATX 3.0 PSUs.

These deliver more power in a smaller area, thus not taking up as much PCB space in comparison to traditional 6- and 8-pin PCIe connectors. Any space-saving trick is a must-have for these hefty graphics cards!

What’s more, combined with an ATX 3.0 PSU, your gaming PC will be able to effectively handle any unexpected GPU power strikes, along with boasting improved efficiency and power consumption. "

Probably a case of NVIDIA innovating with something the rest of the industry does a few years later. I.e. same as with ray tracing, AI upscaling, VRR, you name it.

Because of course a single cable with additional sense pins is so much worse than four eight pin "dumb" cables.

And on the PSU side, the single green 16 pin connector replaces four of the blue 8 pin connectors.

Well yeah it saves a bit of PCB space but thats not important, not sure its actually a requirement to absorb spikes, and in all honesty Nvidia should be designing their GPUs to not spike so oddly.

Yes, your electrical engineering knowledge is better than Intel ATX developers, NVIDIA and everyone else who will switch to this standard.

Ok I wont bother if you reverting to that as a basis of your discussion.

The engineers for AMD/Intel dont agree with you yet though.

Intel literally wrote the ATX 3.0 spec bud.

Intel Introduces New ATX PSU Specifications

ATX 3.0 and ATX12VO 2.0 support next-generation hardware power demands.

12VHPWR was not an Intel specification, it was introduced by Nvidia and Dell long before ATX 3.0 became a thing, you'd think after so much time people would finally educated themselves over who did what.

And it seems Intel revised the connector to something less problematic hopefully.

Don't bet on that, while it may be technologically sound or even an "innovation" but ultimately economics will determine its fate. Now if it weren't for the unfortunate war in Europe & spiralling energy prices I might've seen this take off eventually, but now I'm not so sure.

This is a sensible take.

I thought of this, and while I agree to a point, I still think the connector will be the new standard, though in that same breath I do think GPU power consumption must yield at some point.

To me it only really makes sense on cards that would require 2 or more 8 pin connectors. So AMD will probably support it at some point for the 8900 or 9900 class products but Intel probably not due to them likely not competing in the high end.

Why did Intel push for improving the 12vhpwr-connector when they don't even utilize it themselves? The ARC cards are still 8-pin PCIe.

They are improving it for the same reason bleach says don't drink it on the bottle people are idiots and they need to make it idiot proof.

Wait are you telling me you're NOT supposed to drink bleach? It tastes great over the rocks with a twist of lime!

I suggest a splash of Ammonia. It makes it smell great!

Isn't the physical part of the 12VHPWR connector just a copy of the Nvidia 12-pin used on the 30-series?

 

[onetap]

One cable, with a native PSU that doesn't split it into 8 pin connectors, is much more convenient.

My SF750 has a custom cable that terminates in 12VHPWR so there's no need for an adapter, but native is still better.

Is it important for future Nvidia gpus to have a direct 12vhpwr connector in the power supply? For example, the CORSAIR RM1200x Shift does not use this connector on the psu, but the Seasonic Vertex gx 1200 connects directly to the psu with a 1x 16 pin to 16 pin cable. Which one is more logical to buy for future GPUs?
