ASRock's TempGuard Failed to Stop a PSU-Side Connector Meltdown on a $15,000 RTX PRO 6000 Rig
A repair shop technician has reported another melted 16-pin power connector on an ASRock Taichi TC-1650T PSU, paired with a $15,000 NVIDIA RTX PRO 6000 Blackwell Workstation Edition GPU. The former ships with native 12V-2x6 cables carrying ASRock's own NTC temperature sensor. According to the technician's Reddit post, the connector failed catastrophically on the PSU side and melted into the socket itself, even though both ends of the cable were fully seated. The GPU reportedly survived, and the damage was confined to the power supply side. The technician also says the sensor is mounted on the wrong side of the cable, on the ground line rather than the 12 V side it's supposed to watch, which would explain why it apparently never caught the rising heat in time.
ASRock added the NTC sensor and TempGuard system to its 12V-2x6 cables specifically to shut a system down before a connector melts. This time the system failed to catch the rising temperatures, but it has worked in the past. TempGuard reportedly caught a shunt-modded RTX 5090 pulling over 1,300 W, saving its power connectors from melting. On the flip side, this isn't the first time this exact GPU and PSU pairing has run into trouble either, as a similar melting incident on the same combo surfaced back in March. If the sensor placement is really off on at least some cables, that's a bigger concern than one bad unit, especially when paired with a card that costs as much as a used car.

ChatGPT can be just search engine in this case, and behind there may be official article created by real engineers, not bunch of vibe-engineers that vibe-designed this slop connector.
Since you are so lazy, here article is attached.
People learned 50 years ago that connectors, when exposed to thermal effects, can develop issues, only green knights in shinning armor still do not beleive in it.
Your buddy wanted to discuss, but did not know that fretting exists. If you also want to discuss, and do not understand what happens in metal connector on high temperatures, please follow his steps.So, everyone disagreeng with every time same few green knights in shinning armor is clown?Well, in your reality there is 50 million cards to be potentialy endangered, so... yes, we definitely are not on same reality.Oh, my God, what kind of forsaken reality this is? What kind of reality it is, when you allow numbers to cloud your vision? Be open-minded, believe, embrace green god and it will be much easier for you.
Looks to me like 12vh is much safer. At least it doesn't burn 150w cards like the 8pin used to. Oh yeah, found some 1060s and rx580s with blown and melted connectors too.
Lets use 8pin forewer... No-one said ever 😁
Well, I guess then all is solved - no one should worry about anything. Just enjoy the smell of burned plastic. All RTX5090 will anyway die out in 2 - 3 years and problem will be solved.
I mean, your logic here is undisputable - if people dies from plague in 1327, then why it is issue to die from plague today?
And why should we expect same safety level from new things like we used to expect from old ones? Who cares about that, let's live on the edge.
Guys, you are not clowns, you are whole circus. And current show is quite sad.
A red flag should have trigger the alarm when Cablemod, BeQuiet, Seasonic, Corsair came with the no bent cable rule. Some ppl believe NVD communicated that to manufacturers.
Seasonic - 35 mm - PSUs user manuals
BeQuiet - 40mm + "do not bend horizontally"
CableMod - 35 mm
Corsair - 30mm
Besides, many PC cases doesn't permit that anyway, even expensive ones(Lian Li, NZTX etc) side panels are too close, even newer ones like Lian Li 207. Good luck in not bending the cable( oh! but you can buy risers kits from them 100+/kit) another paracetamol. Is strange how the puzzle takes contour.
One of the latest cases from Phanteks
Such "guideline/rule" is unprecedented for a power cable targeting end users.
Would you tell your wife/girlfriend to not bend the pwr cable of her hair dryer pulling 2000W of the wall? Is not a challenge, just don't do it.
Even the poll is correct still looks very bad for the 12V. Bravo.
Another case of planned obsolescence or we should assume they went cheap for gaskets and that is all there is?:laugh:
Not a question if but when and where you want the balls, under the core, VRAM. It won't blow! just die, no fireworks, sorry. They quickly adopted that LM crap in laptops and GPUs : Asus , Gigglebit, MSI, Lenovo etc.Hidden - no , is in plain sight
Theory - no, they practically melt and are hot to touch, some of them bubbles up
Conspiracy - no, 4 % /5 years, 3.3% in 19 years --- your own data:slap:
The cable is not for end users. The cable is for computer builders. If end users are allowed to buy components for building PCs, they should follow normal PC building gudelines - that includes properly mounting internal cables with a necessary strain relief for plugs.
Can you rationally explain, why are you mixing internal cables in a computer with external cables for movable household appliances?
I think you should try to employ the part of your brain used to search and add stupid illustration pictures with rational thinking, self restraint and self correction, before you post something. Because the amount of nonsense in your posts is truly astonishing.
So, you kinda left this discussion in style. Why coming back? Your shift started, other guy had to go to real work, or what?Normal guideline is avoiding bending cable for 35 mm? Can you find another example in PC builidng guidelines of such brilliant practice?
I though it is so easy to understand, that I did not explicitly put it in one sentence.
Question is rhetorical, you do not have to bother answering on it.
You and your colleague with Sapphire 9070 sample actually did far more to prove that connector is junk than any of us.
It is the most basic rule of building electrical and electronic equipment. The fact you do not know this principle is VERY hard to explain.
Of course, you kinda shared all data we need yourself when you started discussing 50 million cards instead of few hundred thousand, but don't allow reality to cloud your imaginary world.
So, we have all data we need to conlcude connetor and electrical design are junk, we clearly understand why issue is happening. What we do not understand is how you and your side-kicks don't feel stupid trying to defending something that is indefensible ?
Also rhetoric question, don't bother answering...I asked for ONE example... Waiting...
You did tell us we are clowns, so yuu kinda started first... I was just thinking - if you are kind to us, it is basic decency that we are kind to you.
Still, there is 50 millions of reasons why one should not be kind with somebody playing coy... but never mind, we are all decent people. We understand.
In other words while the reports of power cable failure may or may not, be exaggerated, there seems to be something to be concerned about. The risk is not zero.I agree here. While you can't totally eliminate user error the idea a user can still do everything right and end up with the same problem means the solution was wrong, or at least not good enough. Compounding that power connector placement and cases also make it difficult to adhere to the "after-the-fact" guidelines. The user should never have to worry about PC fire hazard during normal operation.Well....that's a tough call. At 2000W I might be inclined to issue a family PSA.
The only difference between 12vh failing and 8pins failing is that the former is making news in techsites, the latter didn't. That's it. They are all based on reddit posts, but people think the former is more important cause they made it into a news article.
I'm not an EE but it seems to me after reading ad nauseam arguments back and forth (not just in this thread) that simple multi-wire/multi-pin redundancy simply doesn't provide enough of a safety margin for consumers for high wattage GPU applications. Consumers shouldn't feel they have to buy a wireview pro II to protect their purchase from self immolation.
I'm willing to concede reports of the high power adaptor melting could be way overblown, however after learning more about how GPU power delivery has changed in the context of the controversy I would personally be worried about running a high power GPU so much that I would just go with the Asus bus powered solution and skip all the wiring issues complely.
Is just 1 page back I explain the same thing but you beating around the bush like a drunken pirate for the glass eye.Plenty of videos GPU repairs, take your time, you'll learn a thing or two, maybe just maybe you'll learn the root cause of failures in 5000 series. Not holding my breath though.
Not even official TDS that clearly show how connector is unfit for its purpose are argument.
It is all la-la land in their world.
They wouldn't sell to anybody GPUs in the boxes with manuals to download and read or PSUs if those wasn't intended for end users to install.
Repair shop guys argue that the 12VHP should have 2 clips on the side to properly secure it, guess what they never said that about 8 pin one. Why????:kookoo:Yes. If I compare it with 8 pin connector wasn't good enough:nutkick:Next will be the 4 slice toaster 2500 W and the electrical wires from a Hybrid car.
Users didn't install the 8 pin plugs with any strain relief in mind yet it didn't melt.
They also bought cheap pigtails from ebay 2$ /piece, still didn't melt. Miracles.I think you should do what you said you'll do
Besides ... sticking around too much might show others, which didn't have the "pleasure" yet, to see your true colors.... of a Clown
