As an electrical engineer, I have been appalled for years at the computer industry and how they do not ever use appropriate connections for the voltage/current level present. The standards are based on costs, and not electrical requirements. The current generation of computer connectors would never be acceptable in any other industry for 12V at the amperage levels presented. It's the standard/spec that is the problem. The connectors are literally half the size they would normally be in any other industry. It's a matter of physical size of the contacts, their separation, and materials used as insulators. All wrong. Add to that the erroneous concept of using multiple contacts and wiring to deliver an overall 12V/55A spec is borderline negligence, since using multiple points to deliver the same power means your chances of failure are multiplied by the number of contacts. You do not spread power across multiple points. You use a single connection and wiring to deliver total rated power with pro-rating. Imagine using such a multi-connector to connect your battery in your car even if it's huge. There's a reason it is a single pair of contacts, one hot, one ground. This multi pin configuration for high power 12V connections is unique to the computer industry and it's poorly engineered. There is no difference between a power supply and a battery. It's still delivers voltage and current. Have you ever seen a battery connected with more than two wires (/-) and connections There is a reason for this. You'd think the computer industry have found a way to avoid the reality of physics. They have not. They went cheap ... and now consumers are at risk.

I know they wanted more power in less space, but they should have just stuck w/ the original limits while replacing two 8-pins w/ one 12-pin. Each sense pin should authorize 150W constant, 180W peak. Want to offer more than 300W constant, 360W peak Your card will need a second 12-pin.
Longer-term, it's time for a GPU form factor rethink. The growing weight should have been our first clue, but now we need to guarantee 2.5mm of clearance above the plug I have a Corsair 7000D, and I doubt I really have that much room between the plug and the glass. If GPUs get much bigger or heavier, we're going to need to start designing everything around vertical GPU placement, including front clearance for the fans, rear clearance for the riser ribbon cable, etc..
Or, and this will garner some controversy: maybe it's time to rein in GPU TDP. I'd like to see the 5080 head back down into that 250W constant, 280W peak territory of the 2080 era. Yes, it's going to lead to some disappointment for a generation, maybe two, but Nvidia is making enough AI money to take a temporary hit here, and AMD and Intel don't seem interested in challenging Nvidia's dominance of the high-end or ultra-high-end segments.

What was wrong with the 8 pins of old again These new adapters are so massive and half the cost of a high end power supply by themselves. Why not just use an aviator plug
At $45 per adapter, You'd be better off bodging 14 gauge wire from the GPU directly to your PSU at this point. better yet. BUILD YOUR OWN ADAPTER. Its really easy to crimp pins and plug them in to your connector housings. People make individually sleeved cables this way and you can easily upgrade the materials when you do so.
There are way too many versions of these new high power connectors and I wouldn't trust installing them in my now several thousand dollar GPU. The human race has had an understanding of electricity for an awful long time, we shouldn't be wasting this much time on a simple power connector.
Edit: If your daisy chain connectors that YOU provide void YOUR warranty, Do no sell daisy chain connectors with your product, period. If they came with the product I'm going to assume they're okay to use with the product. This is just bad on Silverstone's part. if you give someone a part that can cause damage, its going to cause damage.

Aside from going the fully official certified 12V2x6 PSU and 12V2x6 GPU, use MODDIY 12VHPWR cables. Unlike the over-rated, over-priced, and dangerous CableMod ones, MODDIY are fantastic. I use one that is 2x PCI-E 8-pin on one end (to my older, Antec HCP-1200 PSU) and 1x 90-degree 12VHPWR on the other end directly into a 4090.
I have run this at 550-600 W stress tests and benchmarks for probably hundreds of hours over the past 2 years without the slightest issue, ever. I've also disconnected/reconnected the cable from/to my GPU probably like 20 times.
The cable, along with a different vBIOS (you need both), also allows me to overcome the stock 450 W power limit of the MSI Gaming Trio 4090 since the default MSI-included cable is physically locked to max 450 W due to only have 3, instead of 4, sense pins (each sense pin allows a further 150 W).
The MODDIY ones are designed and manufactured properly. Obviously be extra careful & firm to make sure you press the 12VHPWR side/s in all the way but that's just common sense.
Forget CableMod. Go ModDIY.

Thanks Steve!
Also THANK YOU for showcasing Aris Mpitziopoulos of Hardware Busters. He is a GEM of a fellow!
Well hell.....
I would love to have a super, awesome, deeeee-luxe 4090 level performance card but since the neu-powa connexxtror!!! fiasco got hot and heavy I had decided I want NO part of paying $2k for a card that could just kill itself if I did not babysit it. And it could possibly incinerate my abode. I think a 7900XTX with only 80% ish performance for 50% the price and only consuming 350 watts and no reported self immolation/ self-harm statistics... so far seems more my speed. Oh, it also does not have the requirement of the bestest, newestest fancy connector either. I understand design ideas that embrace improved thinner, high-power to facilitate... something... but honestly it looked awfully gimmicky as in an APPLE level of design gimmickyness. If you make the connector thinner but I have a dongle two to four times the size of a regular dual 8 pin set of connectors I DO NOT SEE THAT as a win. Just call me an old fuddy duddy.

I'm so happy I sold my garbage gaming PC. I pre-ordered a PS5 pro. I'm so excited to finally be able to simply game and everything just work.
Our peripheral simply work with all games. I can own physical copies and not just borrow things digitally. I can easily transport it when I go places. And I get a consistent coherent fun experience that's refined with an epic controller with really cool features.
PC gaming is a terrible experience. There's always something wrong something glitchy something not working correctly some kind of troubleshooting needed or required. Steam is such a dull benign and boring experience unrefined including the 20 different launchers you need for other games.
And yeah you don't own any of your games. You can simply be banned by steam for some frivolous retarded reason and there you go all of your games are gone. I'm good PS5 pro is where I'm headed.
Performance is enough for me to be okay with it.

I'd like to thank you for the tips managing 4090 cables. I have a new PSU coming in the mail today, since the high power cable on the current one failed.
I experienced black screen crashes when playing Enshrouded, a game still in early access, and thought they were the game's fault. Turns out the high power cable that came with the PSU was slowly dying. I experienced one final crash, this time on FFXIV, and nearly panicked thinking the GPU died. I tried the adapter that comes with the GPU to be sure, and it still works.
But that PSU, aside from having lost my trust, doesn't have enough sockets to also power Hyte's THICC Q CPU cooler, so I'm replacing it with an NZXT one with higher wattage, future proof with ATX 3.1 and PCie 5.1, or something. And I know NZXT sells replacement cables, dunno about the old one, so if Enshrouded DID have something to do with the problem, I can just get a new cable next time...

I've worked as a terminal contact subject matter expert in automotive connections systems now for 13 years, and your investigation parallels any one of the professional root cause analysis I have worked on in that time. Great work; Linus eat your heart out you little weasel.
I am concerned that the manufacturers of these products are seeing the same issues that we may see in the automotive industry due to extreme vibration profile validation testing, and/or very high ambient temperature validation (150 degrees C or higher for at least a continuous 1008 hours), where their products should only be sitting quietly in a computer case at comparatively mild elevated ambient temperatures. Seems like they need to take a step back and get some consultation for high power connections.

What I would like to see: a return to the level of safety over provisioning the previous 62 pin specification. I have not done the math, but if that means the new connector is rated for 400watts, so be it. As Dr. Ian Cutress would put it. 'That's my minimum specification. Reducing safety margin while making something more difficult to install correctly is bad enough, that's on PCIe-SIG. But pumping more power through it willingly is on Nvidia. (Although the blame may come back to nvidia in both cases).
Personally I think the solution is to make the motherboard the video card and use CPU cooling solutions on the GPU Die. As well as making the power delivery through multiple ATX 8-pin (motherboard style; without sense pins). Up to 4, 2 for GPU, 2 for CPU.

What I find most odd about all of this is that the cards themselves are just getting bigger and bigger. It's not like there is a shortage of space to put a suitably beefy connector on the card if you just made the PCB a bit bigger.. it doesn't have to be so small.
Does anyone remember the first cards that needed external power (might have been the voodo 4 or 5 maybe) it was just a 4 pin molex connector with great big blobs of solder on the back, prone to shorting out. I used to cover the backside with electrical tape, if a stray dust bunny got anywhere near it it would be nasty.

Dude, powering 300W GPU with a single daisy-chained PCIE 8pin cable just sends shivers down my spine. I mean, sure, you have 2 connectors but that power goes through as single cable and terminates into a single plug (in the case of a modular PSU). That is literally asking for trouble.
I actually find these daisy-chained cables annoying as I never use the second connectors and I have to try and hide it to not look iffy inside the case. In my eyes it's a pointless design that, as shown in the video, can lead unaware users astray and straight into failure.

55A X 12V = 660W in the apartment we don't have such a strong fuse for 55A and they send them through small connectors and cables! Due to electrical faults, domestic heaters are created at a lower ampere consumption, so why not expect problems here as well. My suggestion would be to change the power supply standard for graphics cards from 12V to 24V! And thus the graphics card takes responsibility for the conversion. Voltage in Amperage and with the 24V standard The thickness of the cable also changes.

They really need to get rid of the idea of stuffing such a high-power, high-airflow, high-heat GPU into a computer case. They need to find or make a suitable data connector, then put the GPU into its own case with a built-in power supply. That way it would not only have solid power lines, it also would have the space needed for a proper cooling solution using larger heat sinks and fans. There are plenty of space heaters out there that show how such a case can be built.

I'm so concerned to start up my new 4070S now, I think I'll drip some liquid metal into the connectors to ensure propper conductivity.
Jokes aside. If we want to use smaller connectors and cables it look's like it's time to step up the volts to 24V or 48V to lower the amps. Including an auxillary 48V-PSU costing about 50 bucks until PSU-manufacturers implement them into their units seems not to be that big of a deal when selling a Graphics card for 1000$

I have a 4070 FE with the CableMod StealthSense connector and I have been experiencing random PC display freeze and then auto reboot. I have ruled out bad RAM, PSU, power fluctuations, and about the only culprit left is the GPU itself and the only part of that equation that is different is that I swapped the bulky Nvidia connector for the CableMod, so I may need to swap the Nvidia connector back in and see if that resolves it.

makes u laugh that shills like jayztwocents who endorsed cable mods right angle adapters as soon as they were released saying they fix the bending of the cable issue that was causing them to catch fire. doing full on dedicated videos on them without seeing them actually adopted and tested. then when they all started catching fire and the recall happened, they pretend like they werent the ones pushing them in the first place.

so with my GPU a 4070TI I use the cable included with the GPU. am I basically ok with that or what should I look for as I am concerned my older GPU could have this risk I bought the card 5 months ago but it still was manfactured in jan 2023.. the vid was a little confusing and I want to be sure I will not suffer the melting pins issue.. I do have the adapter fully seated I just checked with my flashlight.. thnx

I don't understand this obsession with reducing PCI-E connectors on GPUs, especially not when considering nVidia's cable squid abomination adapter. I'm currently running a 3x8-pin card and I had no issue routing to make it look like there is a single PCI-E cable going to the 3x8-pins, and a nicely managed 3x8-pin is a LOT cleaner looking than a squid, and IMO, just as tidy looking as a true single 12VHPWR connector.

The real issue is, that no one is preventing Nvidia or AMD to come out with a 1000W GPU. Each new GPU release is just a bigger card with more power usage, there is no real improvement when looking at performance/power usage. I would just cap the GPU's at max allowed power drain at 400W and even that is huge! With the cap the manufacturing would be forced to innovate instead of scale.
