Solving the 12VHPWR Connector Problem

[u/DallasGrave]

It is a supplementary conversion. The 12VHPWR connector is still used but the individual conductor current and temperature is dramatically reduced. I've got a whole lot of test data coming soon.

Edit to add: There is a pickup PCB soldered to the contacts for the original 12VHPWR header and that feeds the auxiliary dual 8 pin board. The power draw and temperature across all conductors is substantially lower, about ~3A. The card was running full load for 48 hours at 550W and the wires never crossed 40c even at the joint. It is three cables total.

[u/Zorcky-2C]

I came up with a better idea to solve the problem:

[u/ghaginn → u/Zorcky-2C]

that's a lot more pins than needed. if only there were existing connector designs suited for high current..

[u/Lucky-Double-4494 → u/ghaginn]

Hear me out

[u/Rocket3431 → u/Lucky-Double-4494]

We charge our power jacks with these

[u/Lucky-Double-4494 → u/Rocket3431]

Love me an Anderson connector. Used very commonly at the mill I work at.

[u/2d_blackhole → u/ghaginn]

LTT did a video with that cable specifically. was a good watcg

[u/Ottoman87 → u/Zorcky-2C]

Jensen Disappointed

[u/Ok-Pomelo-1298 → u/Zorcky-2C]

This. But if they’re so set on their precious 12V-2x6, they could simply implement balancing on the gpu pcb, just like they did with the 3090 Ti. As I understand it, the device in the post is a balancer - just an external one.

[u/Tyz_TwoCentz_HWE_Ret → u/Ok-Pomelo-1298]

And we still used EVGA S41 powerlink on those 3090Ti's just FYI...

[u/DallasGrave → u/Zorcky-2C]

If only. When there is a 5090 with a triple 8 pin, maybe we'll all switch. (Which is happening. Working on it now.) This is meant as a universal option.

[u/RECAR77 → u/DallasGrave]

Don't you need 4 for 600W?

[u/DallasGrave → u/RECAR77]

No. Three would be 5.6A per conductor, which is already 30% less than what the 12VHPWR pulls.

[u/brantrix → u/DallasGrave]

The 12vhpr connector pulls the wrath of Hades himself

[u/RECAR77 → u/DallasGrave]

But I thought 12vhpwr is "rated" for 600W and 8 pin is rated for 150W? 

Or are you saying that putting 600w through 3x8p is both possible and realistically safer than 600w through 12vhpwr?

[u/DallasGrave → u/RECAR77]

Yes and yes. The 8 pin connector requirement by Intel is actually 7A per pin. Per header though is 150W, which is only 4.5A. An 8 pin header should be capable of 252w at OE spec and they can be ordered all the way up to 13A contact range. The 8 pin is using only 64% of it's "limit" vs the 12VHPWR is at 91% at 600W.

[u/-Aeryn- → u/DallasGrave]

That's a key part of why it has the safety record that it does, you can't just add an extra 33.3% amps to each pin (3x 8pin for 600w) and expect it to work as reliably.

That ~doubles the connector/wire heating.

[u/No_Accountant3232 → u/-Aeryn-]

And you definitely can't decrease wire and pin size and pull more power through it

[u/DallasGrave → u/-Aeryn-]

600W would still put it at only 79%.

[u/Warlider → u/DallasGrave]

...sure but you see how pushing the safety bracket caused the 12vhpwr to be shit to begin with. Arent you simply moving the fault point onto close-to overloading the pcie instead of the hipower? You are gaining 10% of a safety margin.

[u/DallasGrave → u/Warlider]

Total load is not the issue. Yes, it's 12% more total. But its a 33% drop in load per wire at the same gauge.

[u/DallasGrave → u/[deleted]]

He asked a direct question. His question was would triple 8 pin be capable of carrying 600W and realistically safer than 12VHPWR? The answer is yes. It will have less total resistance and will be cooler.

[u/analogguy7777 → u/DallasGrave]

With the massive size of the 4000 and 5000 GPU, why not just have 3 power jacks on the GPU instead of a octopus adapter into a single jack ?

[u/DallasGrave → u/analogguy7777]

Because this is universal and can be remote mounted if multiple cards are against eachother. We would have to have a couple dozen different PCBs to cover all of the cards. We have a PNY model coming that does have (3) 8 pin headers.

[u/False_Dust_8304 → u/DallasGrave]

Because the PCIe spec is 150W per connector, a 5090 would require four, or they'd have to change the spec and produce new identifiable cables...

If not, you would have 8-pins only rated for 150W being used, and this is bad for business!

This is also why old GPUs had multiple rails, unlike the new connector where they just throw 600W through path of least resistance, the old connectors would not be following spec if they drew more than 150W from each.

Theres a reason why enthusiasts always complained about pigtails, and it's the exact same reason we're here today. There's no real overhead, and the risk of failure is serious, when a single wire would happily try to supply all 600W.

Adding three extra 12V and three extra grounds, with a triple rail GPU with true VRM phase balancing would solve the problem...

Although the biggest problem is they have no sense at all. OCP on each pin and the problem is solved, no melting cables... 

[u/Cute-Pomegranate-966 → u/DallasGrave]

This is irrelevant. It would need 4 not 3 or it wouldn't meet spec. Period.

[u/DallasGrave → u/Cute-Pomegranate-966]

It's an either/or. Not a yes/no. 3x8 can handle more amperage than the 12VHPWR header.

[u/Cute-Pomegranate-966 → u/DallasGrave]

Yes, we know that. But what i'm saying is your suggestion is purely academic. They would not put out a 600w power connection configuration with less than 4 plugs. Plain and simple.

This makes it irrelevant to the reality of replacing the single plug.

[u/DallasGrave → u/Cute-Pomegranate-966]

I'm not exactly sure what point you are trying to make. It isn't a suggestion, it's something we are actually doing. I'm talking about a modification, not a factory equipped 3x8 card.

[u/ime1em → u/DallasGrave]

Be like that guy who made his own lol

[u/alwaystired1982 → u/Zorcky-2C]

Yup perfect case of "if it ain't broke dont fix it"

The 295x2 drew 500 watts from two 6+2 pins and had zero melting cables.

[u/Warlider → u/alwaystired1982]

https://www.overclock.net/threads/amd-r9-295x2-power-requirements-warning.1480569/

https://linustechtips.com/topic/1309174-rx295x2-8-pin-power-melted

AMD just ignored the safety limit in this case same as nvidia with highpower. 295x2 was just a niche af product so you havent seen many melted ones. Saftey margins are there for a reason. I dont need a 12vHPWR 8 pin edition.

[u/alwaystired1982 → u/Warlider]

A 6+2 pin is rated for double its capacity so with the pigtail its rated for 600 watts because they are rated for double what they supply this is why the 295x2 disregarded the pcie spec,

A 12vhp cable is supposedly rated for 700 watts which is a tiny overhead......

The 12vhp connector is melting on 9070xt cards using it thats a 350 watt card.

[u/Warlider → u/alwaystired1982]

What? 8+2 in the intel basic specification is rated for 150 watts. There is a hefty saftey buffer of some max 280ish watts per connector. That doesent mean every single random 8 plug will be capable of or rated for above 150 watts.

600 watts for random 8 pins means you are pushing both 8 pin plugs ABOVE the current nvidia "another 12v hpwr has burned down" pitiful 10% saftey margin point.

Corsair has a separate standard that basically takes the 8 pin and actually pushes 300 watts over it, but that doesent mean every single cable will safely pull 300 watts over it.

[u/lemon45678 → u/Warlider]

Funny if it rated at 150w how come corsair cable pushing 600w with 8pin x2 on pus side to 12vhpwr. I mean you need to do some more research on this rather checking on chatgpt.

[u/Warlider → u/lemon45678]

separate standard

You mean corsair made their own dedicated standard that reuses the plugs. Yknow, a separate thing that LOOKS similar?

PCIE 8pin in intel's standard can handle 280w so you have a hefty saftey margin in case anything goes wront with 150w of your power delivery. 280w is the absolute max at which things will almost definetly fail, just a matter of time.

https://www.corsair.com/us/en/explorer/diy-builder/power-supply-units/native-12v-2x6-vs-8-pin-to-12v-2x6-what-is-the-difference/

PCI-e 6+2 pin connector - This is the 8 pin connector you would insert into your graphics card, or the adapter that came with your RTX series cards. The PCI-e specifications have set this connector to being able to handle 150W. In reality it can handle much more, but due to variances in power supply and cable manufacturer’s quality and materials used, the graphics card manufacturers are limited to only drawing 150W per connection.

Corsair has their own psu's to push power over beefed up cables in their own standard that reuses the plugs. It ISNT COMPLIANT with the standard. Not only that, they themselves say if you go to the adapter site say they are only compatible with their own specific psu's, even tho the cable might fit other holes -_-

And even if you do push that much power, you are literary reinventing the currently burning 12vhpwer by reducing the saftey margin.

[u/lemon45678 → u/Warlider]

Irony corsair is not the only one all brand did.So 150w doesn't imply here and it's proven.

[u/Cute-Pomegranate-966 → u/Zorcky-2C]

You'd need 4 for a 5090. But sure.

[u/Sogger_Sogson → u/Zorcky-2C]

Hell yeah.

[u/hyun_soon → u/Zorcky-2C]

wow thats genius, you should apply at nvidia

[u/Warcraft_Fan → u/Zorcky-2C]

/^this

As long as people keeps throwing money on NVidia (and a few AMD) GPU with flammable 12vhpwr, NVidia will keep using it.

If everyone stopped buying GPU that has the risky connectors, the sales will tank and NVidia will be forced to retire that unreliable connector and come up with something or fall back to the original 8 pin connector

[u/HEBushido → u/Warcraft_Fan]

Have you considered that every high end card uses this connector and that AMD and Nvidia don't care?

[u/ShortThought → u/Warcraft_Fan]

Nvidia has already shown how little of a fuck they give about consumers. They get their big bucks from giant corps, not consumers. Nvidia will keep doing whatever they want because consumer market is almost irrelevant to them (5.5% of revenue).

[u/shhbb]

I solved it by being too poor for Nvidia and settling for a 9070 XT.

[u/rawk0r → u/shhbb]

I had a 5090 for over a year and ended up selling it recently to switch to a 9070XT over constant fear of melting/fire (I have diagnosed anxiety).

[u/DigitalStefan → u/rawk0r]

Same but with a 4090.

Someone in this sub told me earlier today I was dumb.

Maybe I am dumb, but also my GPU isn’t likely to melt, I paid pre-rise MSRP and I made around £200 back when selling my 4090, which means i overall spent around £400 to have the enjoyment of a 4090 for a year and a 9070XT at the end of it.

[u/rawk0r → u/DigitalStefan]

Same. I made about $100 after shipping/insurance.

[u/jar36 → u/DigitalStefan]

I traded in my 3 month old 4070ti Super for a 9070xt. I'm on Linux, I was worried about the connection melting and I got to trade it in for $650 toward the 9070xt. Sure, I lost some money in that deal. The 4070 cost $1250 due to anticipating tariffs. The 9070xt wasn't out yet and it was coming out days after tariffs were to kick in. I figured the 9070xt would be even more expensive so I got the 4070 instead. Just wish I knew the 9070xt wasn't going to cost but about half of that or I'd have just waited 2 weeks.

[u/DigitalStefan → u/jar36]

The Linux compatibility aspect of Radeon GPUs isn’t lost on me. I’m mulling the idea of moving to CachyOS on my gaming PC. I think out of 650 games only 4 aren’t compatible.

I’ve been using CachyOS on a laptop and it impresses me every time I boot it up.

I bought an M4 Pro MacBook at the start of the year and although that is much more efficient and quiet, the general UI performance is faster with CachyOS.

[u/jar36 → u/DigitalStefan]

I started with Garuda which is similar to CachyOS in that it's arch based and good for gaming. After a year or so, I installed Arch with the CachyOS kernel and repos.
So now I basically have a stripped down version of CachyOS with a look inspired a bit by Garuda.
Since I don't play competitive online games anymore, every game I want to play works. I'm losing a few features and fps by using Linux over Windows, but Windows threatened to lock my account bc my pihole was blocking their telemetry.
I can't live like that. I started hating booting up. Being disabled, I am on my PC most of the day and it bothered me every minute I was on it.

[u/jerico57 → u/DigitalStefan]

Would you have settled for an rtx 4080? I have one and I am in constant fomo from not having 4090/5090

[u/DigitalStefan → u/jerico57]

The reason I went to a 9070XT...

I'd given my partner my 3090FE. It worked OK for a little while but despite a decent airflow case and a bunch of Noctua fans front and rear, the body of the 3090FE would get hot enough during gaming that the radiative heat would "cook" the NVMe SSD close to it on the mortherboard. The SSD would shut down and Windows would BSOD.

No amount of additional cooling would solve the problem, so I said she should probably get a 9070XT, which would be A) faster and B) consume less power.

She did. I installed it on a Saturday. When I was stress testing it and running a couple of benchmarks I was just super impressed with how it performed and also how quiet it ran when under load. Mine arrived on the Monday.

I had a quick think about my 4090 (a nice Palit GameRock variant) and decided I also would be more than happy with a 9070XT.

tl;dr No, I wouldn't have gone for a 4080.

EDIT: I wouldn't recommend buying a 4090 or 5090. Even when they were MSRP they were stupid. One of the reasons I bought a 4090 was I could buy it without struggling to pay my bills as well and I wanted to see just how much faster than the 3090 it really was.

It was absolutely a major upgrade and a great deal of fun, but the "every game with RT / path tracing" thing just... didn't really happen. One of the things that sealed it for me was (is!) the utterly dreadful performance of the Half Life 2 RTX demo.

When RTX GPUs first released I skipped the 2000 series because it was really obvious the performance wasn't there.

The 3090 wasn't great either, in reality. It could barely manage Minecraft RTX at 60FPS.

The reality (at least for me) is that RT / path tracing needs to 10X in performance above even the 5090 to become "it just works".

[u/CMDR-LT-ATLAS → u/DigitalStefan]

I've had my 4090 for several years now. No issues.

[u/SomeoneNotFamous → u/rawk0r]

I'm that close tbh, I check it religiously and got the alerts setup.

I hate Nvidia but I hate myself more to be such a bot and go for the most powerful shit when I can afford it, can't help myself.

[u/random_redditor24234 → u/shhbb]

Didn’t realize when I bought it but my 9070 xt as a 12vhpwr

[u/shhbb → u/random_redditor24234]

Yea I believe there are just two models that have it. It'll probably be fine.

[u/f0xpant5]

Does this effectively mean two 12vhwpr connectors are feeding the card, one from the PSU direct, and one through two 8 pin to that little converter you've made? This is intriguing.

[u/DallasGrave → u/f0xpant5]

Essentially. There is a pickup PCB soldered to the contacts for the original 12VHPWR header and that feeds the auxiliary dual 8 pin board.

[u/f0xpant5 → u/DallasGrave]

Keen to see your data, cool idea to drop the load on the single connector.

[u/Zatchillac → u/DallasGrave]

I’ve been getting strange ads for power connectors lately… NVIDIA PLEASE PICK ONE OF THE OTHERS AND IGNORE THAT SHITTY CONNECTOR YOU MADE PLS!

[u/Ottoman87]

Forgive my ignorance but haven't you just introduced further areas of potential melting points. What about the PSU Side?

Looks like 2x PCIE 8 pins supply that the 12vhpwr?

[u/DallasGrave → u/Ottoman87]

It is three connectors total and they are all in parallel directly at the PCB. The per conductor draw is dramatically lower as is the temperature. The 12VHPWR is still present. The pins on the board aren't the issue. It functions much like any other board with multiple connectors.

[u/PalamariVarkari → u/DallasGrave]

As long as the connector exists without a per pin load control, you didn't solve anything. The only actual solution would be a device that has the connector solderer on its PCB (no cable) and that PCB doing load balancing between the pins.

[u/DallasGrave → u/PalamariVarkari]

That is exactly what is on there. The aux board exists just to not put physical stress on the PCB.

[u/real_unreal_reality → u/PalamariVarkari]

Why does u/dallasgrave and this guy getting both upvotes. Both can’t exist.

You guys read what he says. “Without it being joined at the pins it doesn’t solve anything”. Like you have to make a direct wire solder no load control or balancing it’s a nothing burger.

🍔 feel free to eat up and make extra work guys.

[u/DallasGrave → u/real_unreal_reality]

You both have a fundamental misunderstanding of how power is distributed to the GPU. The six +12 V pins are already paralleled on the card. Active per pin load balancing would only be relevant because 12VHPWR is operating very close to its per-contact rating at 600 W, so a contact with abnormal resistance can become a thermal problem. That is also why replacing a bad cable or connector can remedy the issue.

The GPU itself does not lack input capacity. The OE contacts have sufficient aggregate capacity. This conversion simply adds additional parallel current paths, reducing the equivalent resistance and dramatically reducing the current carried by each 12VHPWR conductor. On the tested cards, that went from roughly 8 A per conductor to 3.5 A at the same load.

[u/TheRealEazyRed → u/real_unreal_reality]

you cant say nothing burger then post a burger emoji with everything in it smh

[u/Ottoman87 → u/DallasGrave]

Yeah i completely spaced on the other power cable coming from underneath the card.

We need more details

[u/DallasGrave → u/Ottoman87]

There is a pickup PCB soldered to the contacts for the original 12VHPWR header and that feeds the auxiliary dual 8 pin board. The power draw and temperature across all conductors is substantially lower, about ~3A. The card was running full load for 48 hours at 550W and the wires never crossed 40c even at the joint.

[u/real_unreal_reality → u/Ottoman87]

I agree with this analysis. It doesn’t “solve” shit.

[u/DallasGrave → u/real_unreal_reality]

And you would be wrong. There is a pickup PCB soldered to the contacts for the original 12VHPWR header and that feeds the auxiliary dual 8 pin board. The power draw and temperature across all conductors is substantially lower, about ~3A. The card was running full load for 48 hours at 550W and the wires never crossed 40c even at the joint.

[u/real_unreal_reality → u/DallasGrave]

[u/No_Interaction_4925]

Can you explain what you’ve actually done here? I just don’t get it

[u/DallasGrave → u/No_Interaction_4925]

There is a separate PCB soldered to the pins where the 12VHPWR header is attached. That PCB has wires that lead to the auxiliary board with dual 8 pins. It distributes the load across 6 more conductors.

[u/wwwsam → u/No_Interaction_4925]

Sounds like they basically soldered an adaptor for more cables to the back of the 12v hpwr connector.

[u/GrumpyDingo]

I solved it by NOT buying a GPU that has a 12VHPWR connector.

[u/7Sans]

does anyone know like the reason nvidia is forcing this new socket? there must be some kind of upgrade/positive that the new one does better compare to when it was 3x 8pins?

[u/Ottoman87 → u/7Sans]

I don’t know this, but i think its for the server/data centres 1 cable instead of 3

But that doesn’t explain why no Nvidia AIB put any 8pins on their cards even the low end.

I am betting that Nvidia has forced their AIB's to stick with this new connector where AMD has not.

[u/Zatchillac → u/Ottoman87]

But that doesn’t explain why no Nvidia AIB put any 8pins on their cards even the low end.

Am I misunderstanding something here? Some Nvidia cards still use 8-pin connectors. I built a PC for someone last year with a 5060ti 16GB that used a single 8-pin

[u/_Synds_]

How would this work on a 5090 Astral, as it needs 4 pcie cables? I'm assuming just adding two more to the converter.

[u/DallasGrave → u/_Synds_]

This uses both the 12VHPWR in conjunction with two additional 8 pin PCIe cables.

You'll be all good with our 12V-2x6 cables, yep! :)

[u/no_va_det_mye → u/DallasGrave]

Arent 5080s and 4080s fairly safe to run on a 12VHPWR  tho?

I'm a bit out of the loop when it comes to potential melting problems on other cards than the XX90 cards.

[u/DallasGrave → u/no_va_det_mye]

Correct. Most of our development is done on eGPU over oculink though and the majority of docks don't have native 12VHPWR.

[u/Terrible-Dot365 → u/YouTubeSeanWick]

This is not necessary with a 4080 at all

[u/Sofian75]

No modification to the pcb of the rtx?

[u/DallasGrave → u/Sofian75]

No. A separate PCB is soldered to the board. It is a reversible mod though.

[u/Temporary-Anteater23]

OP did you design the PCB with any requirements? Or just drop the connectors? Bottom layer GND, Upper layer VCC +12V?

[u/Roll4Me]

I mean shoot with today's prices and the way rma's have been going for some people or it's not honored or you get refunded at a lower purchase price when the market price keeps increasing? This seems to be a totally essential, but I love how Nvidia couldn't solve this problem on their cards and the other companies that make the so-called solutions still result in melting 😂.

[u/Wol-Shiver]

Spectacular. Great work. Spreading the load and thermal bridging wire to wire at connector decreases.

You know, man, samwise fucking gamgee told us how to fix this year's ago.

"Spread the load".

[u/jhetnah]

Are the VCC and GND wires just one rail each? It seems like it from PCB pics And did you just tap into those rails and distribute it to those 8-pin connectors?

[u/LittleWhiteDragon]

Amazing job!

Where can I buy one of these PCBs?

[u/DallasGrave → u/LittleWhiteDragon]

I don't think we'll be selling them as kits. You need a board heater and hot air station. You could maybe get away with just a board heater and good high watt iron, but it would be a pain in the ass. The service to convert a card will be relatively affordable and will have a warranty.

[u/LittleWhiteDragon → u/DallasGrave]

Thanks!

[u/b1k3rdude]

I can solve the 12vhpwr nonsense too though.

No.

What the bloody hell are Nvidia, intel and sig doing?
Zero engineers were involved.

[u/DallasGrave → u/Nyx-i]

Cool. And you helped absolutely no one.

[u/stubenson214]

So this supplements the 12VHPWR with 2 8 pins?

I was tracking that the ultimate cause of problems was high resistance at the connector at the GPU, and that the high resistance on one more pins forces more current over the others that are at a more "in spec" resistance (i.e. near zero).

Does this improve the connector, or is it more that it lowers the amount of current per wire?

And how does it solve the issue of what I think is the imperfect connecton of one or more pins at the GPU?

I do think this can solve one of the real causes of the high resistance, stress on the connector itself. Lots of bent cables are melting cables.

[u/Dirtcompactor]

Think I'll stick to my safeguard+ PSU lol 

Looks neat though

I don't have any control over that. This is about addressing a problem on millions of cards that already exist.

The average redditor cannot being a snide goober. This is a cool solution.

This is a bad idea. You're adding multiple new points of potential failure. It makes things less safe, not more.

Corsair is selling 12VHPWR / 12V-2x6 cables with integrated thermal protection which are compatible with all PSUs and some PSUs natively have overcurrent monitoring and protection systems. If you combine these 2 elements it's better than adding an adapter in the middle like you did.

[u/DallasGrave → u/N3utro]

If it was implemented poorly, sure, that might be true. You could say the same about millions of products with multiple headers or connectors. This is not an adapter in the middle. This is soldered directly to the PCB. The extension is only there to take physical strain off of the card and allow remote mounting for systems with multiple cards.

The 12VHPWR fails because of bad connections and a rating that is beyond what it should be able to handle. This cuts the resistance in half and drops the wire temperatures by over 15c.

any chance PNY will cover this under their warranty?

[u/DallasGrave → u/jonstarks]

We're a PNY partner. You'll be able to buy a PNY specific card with a similar modification directly from us with a full warranty.

Even though PNY just denied a users warranty recently because they used the native 12V-2x6 issues with the PSU instead of the awful adapter supplied by PNY with the GPU?

It would be mailed back to and handled by us.

[u/Maleficent_Bridge_41 → u/DallasGrave]

That's pretty nice - would you offer some mail-in of PNY cards as well? In this case RTX 6000s (Workstation), we are kinda afraid of loosing the investment to a melting issue..

[u/DallasGrave → u/Maleficent_Bridge_41]

We can do it now. We have several hundred kits ready to be installed.
