It is a failure of a connector. Do not support it, and it will eventually go away.

It's a PCI-SIG standard. It won't go away.

And no, this is most likely not due to the connector.

[-]

If the connector is melting on multiple models for hundreds of different users even with gpus with moderate power draw... the connector is the problem. I don't care if its user error, your power connector should not allow for user error to cause a dangerous failure state. Clearly this connector is more prone to failure than the old style ones, which makes it a bad design.

[-]

viperabyss@reddit

"Hundreds of different users" is about 0.2% of consumer GPUs sold, not even including workstation and datacenter GPUs that use the exact same connector, exact same power draw, but 0 issues.

It isn't the power connector issue.

My personal recommendation is to treat 12HPWR as if it were rated for 300W.

I'd be okay with that 9070 SKU (245W TDP), but those two OCd 9070 XTs can both reach ~350W, as per TPU reviews.

There was even a report of a 5070 with a melting 12VHPWR cable. No one is safe.

user007at@reddit

Hear me out, if you do insert it properly there is literally no problem with it. The problem with it that people apply a normal level of force installing other components, it’s just that 1% which fail do so when it comes to that connector. If you do insert it with a normal level of force and double check there shouldn’t be any of that.

[-]

justjanne@reddit

Even if you insert it properly, if there's e.g. dust on the connector, or after some insertion/removal cycles some pins have lost their coating, it'll affect the resistance of individual pins unevenly.

On RTX 5000 this will cause uneven load distribution, which can lead to fires.

I don't really understand why you've got a problem with what /u/justjanne said. Uneven loads on a circuit melts components of the circuit. Melted components lead to shorts. Shorts lead to fires. Are you expecting aluminum cases to burst into flames, or some other exaggerated situation?

The dust can be one of the triggers for the problem. It's so badly designed it can have multiple causes.

After 30 cycles.

How many times do you plug / unplug your GPU during it's life time? Pretty sure you can count that with your hand.

[-]

justjanne@reddit

In reality, much fewer than 30 cycles have been found to cause this issue.

And while this isn't recommended, some people remove the GPU to properly clean and de-dust their computer every quarter or so. That increases the risk significantly, as the freshly disturbed dust can settle inside of the connector.

That's a perfect recipe for disaster in just one or two years.

[-]

Canadian_Border_Czar@reddit

All the more reason to not use a native PSU. If you use a dongle then you never need to unplug the connector from the GPU.

viperabyss@reddit

Source needed. PCI-SIG's own spec is 40 cycles.

And while this isn't recommended, some people remove the GPU to properly clean and de-dust their computer every quarter or so... That's a perfect recipe for disaster in just one or two years.

Then they don't really know what they're doing, isn't it? We shit on people who use water to clean their motherboard. Why are we giving a pass to people who treat their hardware in a way that is way out of spec and out of norm?

[-]

justjanne@reddit

Then they don't really know what they're doing, isn't it? We shit on people who use water to clean their motherboard.

Well, we probably shouldn't do that either, as demineralised water is a perfectly fine way to clean electronics, and in certain ways superior to isopropyl alcohol.

Why are we giving a pass to people who treat their hardware in a way that is way out of spec and out of norm?

Well, because they're used to electrical devices being built to a much higher standard.

The required standards for electrical devices in Germany would normally require that if multiple wires share a load passively, either each wire needs to be fused individually, or each wire needs to be able to take the full load itself.

With 12VHPWR, that'd require AWG10 per wire, or if each wire is individually fused, AWG15. For reference, 12VHPWR uses in reality AWG16.

So it's not that people's expectations are wrong, it's that PCI-SIG is applying significantly lower standards than people are used to and can reasonably expect.

[-]

viperabyss@reddit

Well, we probably shouldn't do that either, as demineralised water is a perfectly fine way to clean electronics, and in certain ways superior to isopropyl alcohol.

But you're already adding so many asterisks for exceptions that most people don't have access to.

This is like telling people you can build a computer that's submerged in liquid, but didn't tell them that the liquid has to be non-conductive electrically but highly conductive thermally, such as vegetable oil.

Well, because they're used to electrical devices being built to a much higher standard.

Translated: they're used to building a computer with a lot of room for failure, and don't know they're dealing with a high tech piece of hardware that require precision.

This reminds me of how people were accustomed to pushing 1.5V on their 14nm CPUs, only to burn up the 10nm CPUs because it wasn't designed to handle that kind of voltage.

So it's not that people's expectations are wrong, it's that PCI-SIG is applying significantly lower standards than people are used to and can reasonably expect.

I mean, people didn't know PCI-e 8 pin to be able to carry practically 2x the power load of what it was rated for. People were just expecting the hardware to have tons of wiggle room for amateur fuckery, which 12VHPWR does not offer.

[-]

justjanne@reddit

Yes, as required by standards and law.

People were just expecting the hardware to have tons of wiggle room for amateur fuckery, which 12VHPWR does not offer. That's not exactly a PCI-SIG issue.

Electrical devices need to be designed in such a way that — unless you're intentionally fucking it up — you shouldn't be able to cause damage beyond bricking the device.

I can't even cause a fire or any harm to myself by putting a fork in a socket, but the safety margins of GPUs are now low enough that fire isn't just a possibility, but an actual problem.

I know that the US has a different approach to electrical safety, but that's IMO a mistake, and not something PCI-SIG should copy.

[-]

viperabyss@reddit

Yes, as required by standards and law.

Which the 12VHWPR does pass. You think PCI-SIG / Nvidia / AMD can sell hardware in EU that don't conform to safety rules and regulations?

Electrical devices need to be designed in such a way that — unless you're intentionally fucking it up — you shouldn't be able to cause damage beyond bricking the device.

And yet, people can easily short a battery that would not only cause fire, but also potentially cause an explosion. The same thing with EV too, that can potentially catch fire by itself and burn down houses.

You can't design a product to accommodate for situations where it was clearly not designed for.

[-]

justjanne@reddit

Which the 12VHWPR does pass. You think PCI-SIG / Nvidia / AMD can sell hardware in EU that don't conform to safety rules and regulations?

You only need to pass the requirements in one EU country to be able to sell it in the entire EU. As I showed above, 12VHPWR does not comply with the German VDE standards.

And yet, people can easily short a battery that would not only cause fire, but also potentially cause an explosion.

How so? Sure, most batteries are illegally imported, but compliant ones cannot easily be short circuited (as you can see with power tool batteries or batteries for cameras).

[-]

Canadian_Border_Czar@reddit

IIRC the non Ti only has 2 connectors.

The 5070 Ti was like 5 W over the limit for 2 connectors so it has 3 and is theoretically much safer because of that with a lot of overhead.

Its also been a while since I looked at this so I could be misremembering.

[-]

Jeep-Eep@reddit

375 seems to be the safe zone for the standard, no matter the on paper specs. This and that 5070 are just the standard rate of infantiles you'd have seen on the old standard IMHO.

[-]

crshbndct@reddit

I’ve got the Sapphire 9070xt. I’m Pretty concerned now. I do check that the connector is firmly seated and have a PSU with a connector on it, not using adaptors, and my PSU spec is rated for 600w through the connector.

But it’s still worrying. This is my first big-boy GPU and I don’t want it to cause a fire.

That being said I’m undervolted for 96% of the performance at 240w.

[-]

conquer69@reddit

The cable being fully seated means nothing. What matters is the contact of the pins and you can't do anything about that.

[-]

JuanElMinero@reddit

That last part alone already makes it a lot safer.

Checking that everything is fully seated and no cables near the connections are overly flexed or otherwise stressed, you should be good.

With multiple load balanced rails it would be safe. But for some reason the official spec just does not require it.

[-]

hitsujiTMO@reddit

no, it should have been overspeced like every other power connector.

instead they decided to go with zero headroom at every point so it cannot handle any load imbalance, which is insane.

[-]

esakul@reddit

To be safe without load balancing 12vhpwr would need to be 500% overspeced. The real problem is that 5/6 wires can fail and no safety mechanism will trigger. The card will just keep pulling power like always.

[-]

Strazdas1@reddit

and yet even with 150% oversepeccing 99% of the reported issues would not have happened.

[-]

esakul@reddit

A 400w card was able to burn a 660w spec power connector. In this case it was already 165% overspecced. Without seperate power rails, load balancing or shutoff mechanisms, even if it was 200% overspecced it will only delay the failures, as long as a single wire cant carry all 600w safely there will be a risk of burning.

[-]

Strazdas1@reddit

in the case of OP, it was a card overclocked to use more than 600W.

[-]

PMARC14@reddit

I think most people would be pro load balancing required on future connectors, but overspeccing the replacement cable and connector will be as important.

[-]

Plank_With_A_Nail_In@reddit

It can take 800w but most cards using it do not draw anywhere near that, its used in 5070's etc which use less than half the available power.

[-]

hitsujiTMO@reddit

Under spec 662W is all the connector can take. If you have an over connector cable, then maybe you can push it to 800W, but anything just to spec will begin to heat up at the 662W mark.

And that's assuming everything is completely load balanced. Which won't happen naturally.

Exist50@reddit

Skeptical if there's any practical difference in the construction, but if nothing else, they have much lower power draw than something like a 5090.

Affectionate-Memory4@reddit

True on the construction. I'm thinking more about installation and monitoring care. Workstation and server builders won't take "eh looks alright" as assurance very often, and especially not on GPUs that get close to 5 figures at the top end.

The only chance I see for danger with ARC cards is the B60 Dual. If a version of that tries to power the whole board on a single 12-pin, that could get a bit risky. Given we've now seen a <400W card melt, and 4090s were quite melty at 450W, that card could be at risk.

The old school 8pins burned too btw. It was rare and it never set anything on fire. It usually was manufacturing defect that caused it.

In this case you are talking about Sapphire, since they are the ones responsible for this card. AMD isnt as strict as Nvidia when it comes to board design. If they were, this connector would never been used in this card.

[-]

nullusx@reddit

My bad. But none of them has load balancing.

[-]

Zenith251@reddit

Did AMD

As far as anyone has found, AMD's only reference design had 2x8 Pin connectors. You can find that PCB in cards like the ASRock Steel Legend or Sapphire Pulse.

Anything that deviates from that design is likely designed by the card maker themselves.

Media comments by AMD in the past were that, paraphrasing, "they'd allow card makers to make their own decision around 12v-Poor-Power vs classic 8 pin connectors."

[-]

GenZia@reddit

To add to that, it's been mostly 4090s and 5090s that have been chewing up 12VHPWR connectors.

A card pulling 300ish watts saturates less than half of the connector’s peak threshold, after all.

That's not exactly a fire hazard, load balancing or not.

Personally, I won't be terribly surprised if the card was shunt modded. It's surprisingly easy mod 9070s and a must have to push it up to ~3.5GHz.

Next to no reason to point fingers at AMD.

[-]

Zenith251@reddit

There's something I don't think most people understand about the 12vhpwr connector. While it does have thicker gauge wire, 16AWG vs common 8pin PCIe 18AWG, the 12vhpwr uses a smaller contact point.

And 12vhpwr actually has the same number of voltage supplying cables as 2x8Pin, 6 total.

So technically speaking, the odds of a 12vhpwr having connection issues and melting at 300w are higher than 2x8 Pin doing so.

It's a bad design at 300w, and it's a God Awful one above that. All they had to do was make the connector a bit bigger and this whole thing could have been avoided.

If you watched der8auer's videos on the subject, you'll note that all it takes is for one point of poor, or very poor contact to start a slow snowball affect that could take out the whole connector. In some instances, like while using Asus's Astral cards and their software, you can get absolutely horrible contact off of any cable at random. Perhaps this 9070 XT just had a shitty cable, like so many, and the snowball affect occurred.

[-]

F9-0021@reddit

ASuarezMascareno@reddit

[-]

VTOLfreak@reddit

You are probably not going to believe this but the spec actually says the other way around. It states that all lines should be bridged on the device side.

The AMD cards don't have load balancing either. Both AMD and Nvidia followed the spec. It's the damn specification itself that's the problem. The culprit is working for the PCI-SIG.

[-]

Zenith251@reddit

You're right, and that's the weird part for those who don't know:

The first implementation of the 12HPWR cable, the GeForce 30 series, was out of spec. In fact, it was way above spec. Load balancing seemed to have been forced on the AIBs by NV. GF 40 series rolls out, and all signs of load balancing are completely gone. Which is paradoxically "in spec."

You're right, PCI-SIG, and it's development sponsors Dell and Nvidia, screwed the pooch on this one. They screwed it, and have done jack shit to resolve the issue. Seeing all the issues with GF 40 series, NV acted like GPU's self immolating is intended behavior and repeated the design failures in 50 series.

Seeing AIB's, especially ones who don't even make NV cards, doing the same shit is infuriating.

Makes me wish AMD had contractually mandated load balancing if AIBs wanted to deploy 12v-Poor-Power.

PM_ME_UR_GRITS@reddit

The connector is designed in a way that the octopus cables are probably load-bearing for the pin resistance tolerances. If you try and do crimp connectors like PSU vendors typically do, it isolates the thermals and the resistance to individual wires instead of being able to share heat across wires. So one wire gets hot, the pin fails, the other wires get hotter, their pins fail.

conquer69@reddit

The connector itself is ok if there is load balancing. There is no need to throw out the baby with the bath water.

[-]

reddit_equals_censor@reddit

it is literally a 0 safety margin connector with tiny extremely fragile connections.

there is no saving this fire hazard. it is fundamentally broken.

and NO load balancing the individual pins by splitting the vrm can not be used at all ever, because even if it would prevent all melting, which absolutely no one should expect, then that would still be inherently unsafe, because the connector would now have insane pcb requirements on the target, which would also be impossible for certain uses, that can't just split a vrm into half.

just think this through.

it would be the equivalent of saying: "this one wallplug with 12, instead of 2 power connectors is perfectly safe and not the reason it melted when connected to my mini oven, because it is the mini ovens fault, which used the connector wrong."

can you see how insane that idea is. the connector by itself needs to be safe and it is not and it CAN NOT be ever.

you want a small safe connector? alright sure, let's use xt90 or xt120 connectors. both have 2 connections for power (one of which ground and one 12 volt then) and the xt120 connector does 60 amps sustained, or 720 watts at 12 volt.

so again YES you throw the nvidia fire hazard connector out with nvidia.

remember all the people claiming, that eps 8 pins (cpu power connectors 235 watt per connector) need to have their load balanced through splitting it in half? oh yeah NO we don't, because that is insane and doesn't matter and it needs to NOT matter to safe connectors, which the eps 8 pin connector is.

please stop trying to defend this nvidia fire hazard, as if it would suddenly be perfectly fine, if only x would happen.

how many x did we have now?

is x: user education after the wrongful claim, that it is just user error.

is x: the sense pins being too long, but now they are shorter with 12v2x6, so now it is safe

is x: rtx 50 series release, which nvidia claimed will be completely free from any melting

is x: using the adapter, that comes with the card, instead of anything else, because some random people lied about it and claimed, that certain nvidia 12 pin fire hazards were safe, while others aren't, yet ALL ALWAYS end up melting?

can you give up on looking for x and accept, that there is no saving an inherent nvidia fire hazard?

is that possible?

I warned about this too, I was seriously disappointed the Saphhire Nitro model used it and then was later confirmed to have NO load balancing which is the root problem here! The design cannot just handle going without it yet the spec is to have no load balancing, it's stupid.

Now I wasn't looking to buy this gen, I want next gen Radeon if they're good value but dammit I have a Saphhire and Saphhire is commonly called the EGVA of Radeon, they make good cards and stuff. But jeez I really do not want to touch this connector EVER if I had another choice for a GPU unless it is CONFIRMED to have load balancing which then I could trust it because some 30 series had this connector but Nvidia was handling the spec at the time and yeah all of them had load balancing and nobody had the melting issues we now have with 40 series since the official specification without load balancing came out, then 50 series and the odd 9070 XT with them again melting. Just took the 9070 XT this long because only a few specific models use it and then they still don't draw as much as a 4090 even for the OCs, biggest out of box OCs are about 5080 level which is less risky but still CAN melt which we saw here.

How is it possible to know this is the first? Lol the first one posted on reddit is not the first one it happened to.

CauliflowerFine734@reddit

To be perfectly blunt this has to be a user error or a QC failure because plenty of 5070 ti and 4080 super exist that have NEVER failed on this connector as a result of anything BUT user error and QC failure.

It's Ngreedia's fault.

Let’s wait for tech YouTubers to really hold AMD accountable here. Lol

[-]

angry_RL_player@reddit

Why? Nvidia is the one who forced everyone else to adopt it.

[-]

Dreamerlax@reddit

Well most 9070s are not using it so...

[-]

JuanElMinero@reddit

Yup, for some numbers:

1 model out out of ~15 different 9070 SKUs
2 models out of ~20 different 9070 XT SKUs

That's with all the OC/non-OC and color subvariants excluded from the lineups.

It wasn't an AMD decision to use it. Amd's reference designs do not use it, but they allow their board partners the freedom to choose what connector and implementation they wise to use. In comparison, Nvidia actively forces their board partners to comply and use thr standard.

[-]

Lille7@reddit

Its not a reference AMD card though, AMD uses 8 pin. This is 100% on the board partner and the shitty connector.

Aggravating_Ring_714@reddit

They will find excuses to not do it // why it’s probably Nvidia’s fault this happened 🤣

shugthedug3@reddit

How does that happen with a 300W TDP? you would need a lot of the pins to go high resistance to result in overloading the remainder.

When it happens to 5090s the margins are much slimmer due to much higher power so even one or two pins going high resistance can cause overloading.

They really need to start implementing fault protection at the PSU end.

I'm kinda happy I went with the 9070 XT Red Devil from PowerColor, which has 3 connectors.

[-]

Tenelia@reddit

I've been with PowerColor for generations... Anyone has any idea how the current gen cards are like? I'm still on Vega 64 and runs Witcher 3 perfectly at 60fps with all my mods...

[-]

HuckleberryWeird1879@reddit

Just buy a Powercolor then. I have a Powercolor Hellhound 9070 and it's so quiet and runs like a beast. And it has two 8pin.

[-]

TheZoltan@reddit

I saw the Reddit post for this earlier. I think the guy was using a super budget 700w PSU so it makes me a little less worried. Hopefully this doesn't become a common problem as I love my Nitro lol

[-]

Yebi@reddit

For this particular failure it does not matter what PSU you have. None of them have load balancing on the supply side

[-]

BogiMen@reddit

It’s a low-quality PSU, but I don’t think the cable failed because of it. It has low 12V rated power, and its protections aren’t tuned well. I’m not an expert, but the only way the PSU could cause this would be through a crazy transient spike - and this PSU seems to be within spec. Back in the day, I personally built more than a dozen PCs with Chieftec PSUs (also 230V) together with Radeon GPUs (which were power-hungry but offered good bang for the buck), and I never saw an 8-pin connector fail.

[-]

fkenthrowaway@reddit

Can you believe that a simple xt60 connector would be enough and problem free?

[-]

MrDunkingDeutschman@reddit

Weird because for cards of the 9070XTs power draw you can barely find any cases of burned 12V-2x6 cables. 99% are 4090s or 5090s with a few extremely rare 4080 and 5080s. Never seen an affected 300W TDP nvidia card.

[-]

SireEvalish@reddit

The 9070XT is probably far less common than the 4090 or 5090.

[-]

GenZia@reddit

If you discount shunt mods, that is.

[-]

F9-0021@reddit

In these cases it's most likely due to extenuating circumstances like the cable not being seated fully. Lower TBP shouldn't lead to runaway heating, even if all the load passes through one pin.

[-]

Active-Quarter-4197@reddit

the 9070 xt can draw as much as a 5080 so I can see it

[-]

MrDunkingDeutschman@reddit

With RT on they have the same power draw. If you're looking at a less conservatively tuned card than the FE the 5080s RT power draw is higher.

Didn't expect the 9070XT to draw 350W in raster though. That's really mad.

[-]

Active-Quarter-4197@reddit

https://www.techpowerup.com/review/asrock-radeon-rx-9070-xt-taichi-oc/41.html

yeah an the taichi goes to 365 lol. The AIBs on amd really push the cards to the limit lol. I think the nitro xtx pulls almost 100w over the reference xtx stock

[-]

Pijany_Matematyk767@reddit

I think nvidia is more strict with the AIBs

Yeah it is, Nvidia is very strict with what its AIBs are allowed to do. AMD is more lenient and lets the board partners decide more on their own and Intel is the most lenient, more or less allowing anything so long as the AIBs promise to handle potential warranties/returns

[-]

N2-Ainz@reddit

That guy used a questionable Kolink PSU

[-]

NGGKroze@reddit

pair a card that constantly hovers \~360-400W power usage with connector that has problems and OLD PSU that doesn't have native support, rather use adapters and you have your receipt for disaster.

Also connectors rating falls down with temps. So with the lack of load balancing as well and potential lower Amps per pin due to heat plays a role here - we saw some crazy temps with 5090s connectors (albeit that was 600W+)
