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

[TheDeeGee]

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

8-pin can do 340 watts.

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.

The adapterconnector can't be that bad, considering it just got standardized with only a few changes.

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?

Early adopters. You and I may not be among them, but we still have to thank them for pretty much every device we take for granted.

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

Read the entire 4 page one on Igor's lab. There are quite a few internal changes especially to sense pins along with new classes of Power delivery.

So what about ATX 3.0 PSUs .. ? I have an ATX 3.0 Dark Power Pro 1300W PSU with 2x modular 600W 12VHPWR cables

Suppose I buy an RTX ~5090 in the future that will have the new 12V-2x6 connector - what about the PSU

Will there be adapters (lol) from 12VHPWR to 12V-2x6 ?
Or PSU makers will provide new 12V-2x6 cables (at least for modular PSUs) separately ?
Or everyone will have to buy a new ATX 3.1 PSU /w 12V-2x6 ??

Or I just keep using my 12VHPWR cable as is and hope RTX 5090 doesnt melt?

Well, Igor's article says they're still gonna be inter-compatible, but it's great to see progress here - I'm still a bit paranoid regarding the adapter and occasionally check whether it's seated completely, haha, even though my 4080 is 2x8-pin and limited to 300W.

The bigger question is, in my opinion: what about people who already bought new PSUs? Those are being kept for way longer than videocards.

What can I say, when you have hundreds of watts going over a handful of cables, it can't hurt to check things once in a while. Better safe than sorry.

 

[sLowEnd]

150W & 300W are new modes?

I thought they already existed:

What about atx 3.0 power supplies just released and under development?
People buying components will try to skip a full generation of power supplies at all cost.
Losses for companies and e-waste.

It doesn't look like it would take more than an adapter. Or the proper cable, if your PSU is modular.

That is the main point.

What about all ATX 3.0 psu with 12VHPWR developed and under development, who is going to buy them from now on?

Somebody didn't want to pay licensing costs to Amphenol (and they might even get a discount as the technology is at least a decade old).

Up to 36 amps per contact, 200 mating cycles, works in servers (meaning, it works).

Create a new revision and replace the connector? There don't seem to be changes on the electric front.

I don't understand why they're continuing to use Micro-fit instead of MiniFit Jr.

All the problems we've seen so far have been a result of pins making poor contact, or pins generating heat. Using smaller, fragile pins and condensing that heat into a smaller space is the obvious cause, and the larger MiniFit Jr. has been working incredibly reliably for the PC industry for 25 years.

It's not like physical space is an issue on the latest generation of triple-slot, extra-long, extra tall GPUs, so why the obsession with using this clearly-flawed, compact connector for more power handling than any other connector in the history of x86 computing?

 

[TheDeeGee]

With the shortening of the sense pins i forsee a lot of failing system boots.

Also Astron (3-dimple) needs to banned from 12VHPWR cables, it's so unreliable. Only 2 out of 6 dimples could make proper contact for example.

NTK (4-spring) needs to be the standard for 12VHPWR cables.

Because big cable/multiple cables = U.G.L.Y.

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.

That seems to be a physical change.


Nevertheless,
Who is going to risk to buy an ATX 3.0 now they'll be awared ATX 3.1 is on the horizon? And the cables? E-waste.
Lots of potential cables and psu will pop up on ebay (and regular retailers) for the uninformed user, which connector H+ H++ H++v2, which pin the good ones whe bad ones?

The regular user wants to "play" or "use" the hardware not be informed about H++ 3.1.
This is like the usb-c mess.

Would be terrible if PSU's became rapid development as well, they the one part you could maybe get a decade out of.

If you must buy now, get a modular PSU and replace the relevant cable when needed. If you already bought a PSU and it works, it will continue to work, because of backwards compatibility.

Because big cable/multiple cables = U.G.L.Y.

Let's not forget impractical. Have you never started to connect plugs only to discover that where the first plug went in painlessly, the second one just wouldn't fit? And not because of the connector, but because there's no more room for your fingers holding the connector?

They changed how it's being done over the sense pins.

The "modular" 6+2-pin connectors has this problem every time...

I predict a rash of PC fires in coming years.

Brilliant way to get rid of future budget-builds as a competitor and drive new sales...

"Oh, my PSU/GPU melted"
"That's your fault, you bought an old PSU"

The fact the connector is getting revised, is admission to the previous version causing damages, no? How do you class-action against an adopted standard?

If it didn't happen already, I don't see how having things standardized can increase the chance of a fire.

"which will be part of the ATX 3.1 spec"

the pc world.......it goes in spurts.........no updates for years, then a bunch of updates in a short time.

well hopefully this addresses all the issues......
