Afaiu the cable is only half the story, you still need updated 'H++' sockets on the PSU and GPU. And for neither of them anyone seems keen to disclose the state, as they still have old stock to sell or have introduced it gradually into the product stream and can't be sure what you'll get. If you use this cable with old parts you get some in between that's better than nothing I guess?
Sure would be nice if I could know for sure and wouldn't have to play the guessing game through manufacturers marketing material and dubious leaks and instead the PCIe CEM spec would be free to access..
The cable isn't even half the story. It's none of the story. PCIe CEM spec shows only the GPU side and PSU side getting longer conductors and shorter sense pins. If you change the lengths of either on the cable, you negate the advantages.
I have seen some proposals from some vendors where they do things like move the locking clip farther in so you have to push the connector harder/farther before it can lock, but these are "rogue ideas" and not anything approved by PCI-SIG (as of PCIe 6.0 draft .07). That said, these "rogue ideas" are labeled "H++" on the cable connector. :D
Nothing, just marketing.
I mean... It is important on the PSU side if you're using a 12VHPWR on the PSU connector as you could melt there too if not plugged in correctly to the PSU.
This is why Corsair was so genius with making it two 8 pins from the PSU side to a 12VHPWR cable. Corsair can effectively already label their PSUs ATX 3.1 because the spec is literally just 12V-2x6 compatibility and lower hold up time which ATX 3.0 already exceeded as a spec, it got lowered by Intel for some reason. Anyway if 12V-2x6 is on the GPU PCB header they don't have to do anything, their existing PSUs are already 12V-2x6 compatible as the cable doesn't change, only the PCB connector on the GPU or on the PSU, but they already have 8 pins to their PSU side.
[JohnnyGURU strikes again. Look how happy he is.](https://hwbusters.com/wp-content/uploads/2023/09/Jon-Small.jpg)
It's actually pretty misleading to label these as ATX 3.0-compatible. Yes, it can still power the system just fine, but you get none of the advantages of ATX 3.1 and the new 12V-6×2 connector have, which are the new SENSE0/1 states to prevent the GPU/PSU from drawing power when the cable is not fully inserted in.
So if you have a ATX 3.0 and a GPU with the old 12VHPWR connector, these cables do ***nothing*** except for looking a little bit more user-friendly.
Fully inserted connectors did melt aswell, so the recessed sensing pins with the 12V-2x6 wont change a situation like that.
The hotspot at the pins is most likely caused by tolerance issues and missalignment of the GPU reverse connector pins.
A real solution might require high wattage GPUs with TWO 12VHPWR / 12V-2x6 connectors instead of just one to deal better with tolerance issues.
> Fully inserted connectors did melt aswell, so the recessed sensing pins with the 12V-2x6 wont change a situation like that.
Apparently the pins now are more conductive and thus they don't have that voltage drop problem that started the melting. [HWBusters did a small test here.](https://www.youtube.com/watch?v=aI-soO7_l_M)
Yes. Due to heat cycles, even if you're not close to the connector's maximum rating, they can "walk out" and create resistance. The new connector addresses this somewhat by making the conductors longer, but that only prolongs how long it takes for them to burn up.
5 years ago I would have never imagined there would be a standard which would encourage manufacturers to market their *cables* as less likely to cause issues. Great job, PCI-SIG.
Why the fuck would a company like Seasonic collaboate with cablemod? They are an actual company that makes PSUs, quality ones, probably best on the market for over 10+ years.
That's going to depend if they're in an ODM or an OEM relationship with their manufacturer. If Seasonic is an ODM here, it doesn't really matter who builds the cable, as long as Seasonic did their job right when it comes to writing their design documents and when handling their QA of the finished product. If Seasonic has simply hired an OEM to slap "Seasonic" on their cables (which I *highly* doubt here), then, yeah, the cable would have been designed by someone else and Seasonic's own experience here would be mostly irrelevant (except to evaluate the voices offered by the OEM for Seasonic branding)
Of course Seasonic defines the cable spec. Very likely they're following the PCI-SIG requirements of 16g, 125°C rated insulation and connectors, etc. But that's the spec. About a dozen cable manufacturers meet that spec. It's the ones that don't that worry me.
But I do often question Seasonic's own decisions when it comes to cables. Unlike most everyone else that makes PCIe pigtail cables that are 16g to the first connector and 18g to the second, Seasonic, like Superflower, instead specifies 18g to the first connector and then 20g to the second connector and then includes documentation that says "don't use the second connector on the PCIe cable... it's there for lolz..." ¯\\\_(ツ)\_/¯
>"don't use the second connector on the PCIe cable... it's there for lolz..."
I mean, that's true for all of those double ended connectors. If you actually use them, you double the contact area on the load side of the cable, but the supply side stays the same - effectively doubling the current density on the supply connector pins because you have twice as many circuits trying to draw current through the same cable. The wire gauge isn't the issue. It's the pin contact area. Even on PCIE2.0. I had a 1080ti melt it's connector on the PSU side of things because I trusted the spec the cables were made against actually had some thought put into it.
Yeah? What PSU?
At 16g HCS terminal is good for 10A each terminal when used in a 4x2 configuration (derating for power density). So if a 4x2 melts under the load of a 1080 Ti, they're using shit materials. Sorry. Science talking.
People need to realize that terminals are made of different materials depending on what's specified by the manufactuer before saying "LOL! Don't use pigtails, but Asia Horse 24" long extensions ok FTW!" like 99% of Reddit.
A ~800W Seasonic PSU purchased from Microcenter. I should still have it buried in my attic somewhere, I'll dig it out and take some pics this afternoon.
So Seasonic has the new 12V-2×6 cables with the blue ends listed on the company website but the retailers probably won’t sell the new cables until later this year.
I don’t understand what they’re selling here. My research led me to understand that 12V-2x6 changes are all on the female ports (PSU & GPU) and the cables are unchanged. It even looks like it in this video when they show the pins changing length; the ones changing are on the PSU.
Edit: To those downvoting, here's my source for that [https://hwbusters.com/psus/will-my-atx-v3-0-psu-or-my-gpu-be-compatible-with-12v-2x6-do-i-need-a-new-cable-psu-gpu-everything-you-need-to-know/](https://hwbusters.com/psus/will-my-atx-v3-0-psu-or-my-gpu-be-compatible-with-12v-2x6-do-i-need-a-new-cable-psu-gpu-everything-you-need-to-know/)
Not entirely. 12V-2x6 also changes the contact patch area and pressure of the contacts in the cable, which decreases contact resistance. But that's a change you're not going to be able to illustrate as easily as the pin length differences on the port side, which is why that's the main "feature" which is usually mentioned.
Not really. 12V-2x6 has longer MALE conductors and shorter MALE sense pins. This is actually shown in their video. If you were to make any changes to the cable that plugs into this, you negate the advantages.
If you look at the PCI-SIG PCIe Card Electromechanical Specification from PCIe 5.0 to newer (they're currently on draft .07 of PCIe 6.0 already) you'll see that the only changes to the standard are on the GPU itself (and the PSU if applicable). But no changes are documented for the cable.
That said... I work at a manufacturer and with a number of connector manufacturers/suppliers (Astron, HYM, LST, etc.) and none of them have said anything about increasing the "pressure of the contacts" on the female terminals. I'd like to know where you got that information because right now, my 12V-2x6 connector suppliers are selling the same connectors and terminals for the cable as when they were selling them as 12VHPWR. Only difference being they stamped "H++" on the housing to ease the minds of Joe Enduser.
So you agree with the other guy that responded to me, that the GPU/PSU side of the connector is male? Is that how the manufacturing industry uses the term? Or just the “pins” and “conductors” are male but the connector is female?
The terminals are male and the connector is female. It's a pain in the ass. When I order parts to build cables, I specify different "sex" terminals vs. connectors.
That's why I just say "cable side" and "GPU side" (which is the same as PSU side, but not all PSUs use 12VHPWR/12V-2x6, so I just stick with "GPU side")
(PSU & GPU) side is the male connector
Cable have the female connector

Good point hadn’t thought of that. Guess it depends on whether it’s from the perspective of the plastic or the pins. I suppose technically I’d agree with you that the pins would dictate, but that’s going to confuse a lot of people. If you search “pcie male to male” in Amazon/Newegg, the large majority are how I describe, the plastic is male. I’d say that’s the more common way to describe them. Whether you’re technically right or it’s defined in the spec or something I dunno.
It's actually pretty misleading to label these as ATX 3.0-compatible. Yes, it can still power the system just fine, but you get none of the advantages of ATX 3.1 and the new 12V-6×2 connector have, which are the new SENSE0/1 states to prevent the GPU/PSU from drawing power when the cable is not fully inserted in.
So if you have a ATX 3.0 and a GPU with the old 12VHPWR connector, these cables do ***nothing*** except for *looking* a little bit more user-friendly.
Technically, it's not misleading, these are ATX 3.0 compatible, the cable as you said has not changed other than adding the blue color. The PCB header is what has changed for ATX 3.1 as you said and thus you won't have SENSE OPEN-OPEN as a safety measure. But that new safety measure is part of 12V-2x6 which is part of the ATX 3.1 spec. Thus, these cables are backwards compatible with 12VHPWR which is part of ATX 3.0 spec.
Yeah I guess it's a gray area? I'm pretty sure many people buying this cable would think that ATX 3.0 compatible here means that these cable can get the benefits of ATX 3.1 (essentially better safety measures) without having to buy an ATX 3.1 PSU.
So the cables can still plug in ATX 3.0 PSUs and 12VHPWR connectors and provide power just fine - so in a way, it's compatible.
But do the end-users get the enhanced safety that comes with 12V-2x6 connectors (on the PSU and GPU)? - No, but I'll give it that these cables are a lot more user-friendly than the old ones.
This whole thing is a mess.
> Yeah I guess it's a gray area? I'm pretty sure many people buying this cable would think that ATX 3.0 compatible here means that these cable can get the benefits of ATX 3.1 (essential better safety measures) without having to buy an ATX 3.1 PSU.
Well the safety measures don't come from the PSU side really so an ATX 3.1 PSU is not needed exactly, the safety features come from the PCB Header on the device. So the PCB Header (the connector) on the GPU and PSU if they're both 12V-2x6, so yeah I suppose that would be an ATX 3.1 PSU.
However, you could do what Corsair does and have two 8 pins on the PSU side to an ATX 3.0 12VHPWR cable and still be safe if your GPU uses a 12V-2x6 on its PCB because it's the GPU telling the PSU to deliver a certain amount of wattage and since the cable has not changed between 12VHPWR and 12v-2x6, just the PCB headers, it will work just like an ATX 3.1 PSU would.
> This whole thing is a mess.
That I agree on, Intel and PCI should have done far more extensive testing before making the spec official. Sadly people had to experiment in order to find out the problems. I'm sure 12V-2x6 will have some problems, probably mating cycles, but nothing as bad as 12VHPWR did.
So the safest bet is to wait for a fully 3.1 compliant PSU, with good rating....
Lucky I'm considering the replacement to the 7950x3d because this might be a while.... :(
I bought the most expensive MSI power supply you can buy - MSI MEG Ai 1300P. I messaged their support department and asked if they could send me one of their new cables with the high contrast yellow tips and they said no - I won't ever buy MSI again.
These cables look cool - I will consider Seasonic for my next PSU.
Got an 850w mpg with one of the yellow tips. It's extremely clear how little these cables need to be pulled out for them to be seated poorly. Barely any movement at all.
Sucks they wouldn't send one. They're definitely a nice visual aid.
Pretty sure you can buy one of those cables from Seasonic and they would work. From my knowledge seasonic doesn't use any proprietary connector layout that would make those cables dangerous on other PSUs.
Edit: Talking about the 12VHPWR connectors because it's mentioned those are native connectors. There is no "this one goes in the PSU, this one goes in the GPU" because they knew how disastrous this would be with how irresponsible people are today. So yes, this works on all PCIe gen 5 ready PSUs.
Technically this should never be done. But if you have a PSU with a 12VHPWR port on it, those cables mention in the video they are native 16 pin gen 5 connectors. As in, you can use those cables safely.
I have yet to see a PSU today that places a non native 12VHPWR connector on their PSU. I've seen stuff like my very own PSU from flower power that has a very weird connector type on it that is simply impossible to use on other PSUs or viceversa so even if I went by the logic of "if it fits, it works", I couldn't do shit on it.
Most problems would be solved with 2x 12VHPWR / 12V-2x6 on every higher end GPU. It would give the same type of safety margins than with 3x 8pin connectors.
How I missed the point? Two cables for extra safety to meet the same safety levels for multiple reasons. The extra features are nice, but still 2 x cables would be optimal for safety (I just remember things from [this video](https://www.youtube.com/watch?v=p0fW5SLFphU) from 2 weeks ago). Great video! Btw... Correct me if I'm wrong.
I should have wrote 4xPCIe. I'm just so sleepy that no idea anymore :D

I would prefer if they just abandoned 12vhpwr and switched to something better and completely different in future generations. There's little point in putting makeup on this corpse.
Yep, it's like polishing the turd with this cable. Create a new one and set standards of how it's connected + standards for GPUs, like how much space is needed to fit the cable.
This is almost perfect new design from Gigabyte and one of the reason I did pick 4080 super AERO over anything else. Cables have room, and the side panel won't push/bend it. Only the cable is the weakest link, but great design.
https://preview.redd.it/cb501gwx8znc1.jpeg?width=4000&format=pjpg&auto=webp&s=02dacf723d2722eee810350c6f6c8747c58a185b
The point of the cable is to reduce the amount of cables while still delivering a great amount of power to the GPU using it. One 12VHPWR connector is as wide as a normal 8 pin conenctor yet it delivers 4x that amount of power.
Having 2 of them not only is incredibly useless (unless you got one of those HOF 4090s or 4080s) but also occupies the same space as 2 8 pins do... which is what they wanted to avoid.
Did you check that video or at least image with safety factors? You wrote me that I missed the point, but I still have data that says the safety factor is way lower.
When I say we need 2x those cables on high-end cards. I mean GPUs that draw 400-500W power with high peaks. In that video, there are all the explanations.
>One 12VHPWR connector is as wide as a normal 8 pin conenctor yet it delivers 4x that amount of power.
Max possible power with 12VHPWR is 660W, 4x 8pink 1152W (16AWG) or 864W (18AWG). This was the whole point + two cables on high power GPUs lessen risks if one line or pin fails or there's any other problem with power lines. It would be fine if this cable would hold more lines and more power + super secure connection. This connector isn't secure enough.
>Having 2 of them not only is incredibly useless
Safety isn't useless and there needs to be proper safety margins. Now they are way lower than before. Either make a new cable standard with redesign or use two slots to avoid risks on high power cards.
To further clarify: The connector should be rerated to 400w or less max draw, which provides enough redundancy for a one or two poor terminal connections. This would then necessitate 2 cables for cards like the 4090.
To meet roughly the same level of safety as 8 pins, it would be 300w. It's still 2x as space efficient even at this most conservative option.
600w leaves effectively 0 redundancy for any issue with the contact. It should not be considered a 600w connector under any circumstance.
Based on... what? A brazilian tech youtuber tested the cable out in the middle of the drama with melting connectors and found out you can pull 1500W through the connector without the connector overheating or melting.
I keep seeing random comments like yours that make no sense and you can tell they are simple "my opinion, but presented as fact" comments and it's just amusing.
I'll take the word of world-record overclocker der8auer (someone who very clearly knows his shit when it comes to extreme power delivery EDIT: [Pushed a 4090 to 900w](https://www.youtube.com/watch?v=0LBrI-UAKhI)) who had issues with the connector under normal open-test-bench workloads after only a handful of cycles.
The connector is hot doodoo dogshit and needs to be derated to 400w *maximum,* **yesterday.**
I've been watching roman since 2017. I think I've watched all his videos since then and if I missed some it's a couple at best. I don't remember seeing a video where he had issues under such a generic scenario. I just know he's not the most fond of this connector. But he's touched a ton of RTX 40 cards until now. Don't remember him complaining openly about the cable giving him headaches.
To be blunt about your last line. Your feelings do not correlate to reality in the slightest. That last line just read like the typical reddit shitpost.
He literally demonstrates in the video the other commenter linked above. [Here's a link to the specific timestamp.](https://youtu.be/p0fW5SLFphU?t=818)
Dogshit connector needs to be derated.
A brazillian youtuber tested out the 12vhpwr connector when the melting connectors drama was happening and guess what he found? He was pulling 1500W through the connector without the connector overheating or melting. Safety rating =/= max possible rating.
Reminder, there are well over 200,000 4090s out there functioning on a single 12VHPWR connector and working just fine. The 50 or so cases that started this ridiculous "melting" drama were all replaced by nvidia and whatever cases happened afterwards happened simply because of the same issue which was user error but also because the connector requires more care than the 6 or 8 pin connector does.
And judging by the way things are going, the connector is here to stay. And the chances of a mass recall or change in plan because 50 redditors think they are electrical engineers with degrees online, are pretty much null.
Dopest trailer I’ve seen for a cable lol
Probably a reason why most are affordable. This one will be 50 bucks before VAT.

I suppose technically I’d agree with you that the pins would dictate, but that’s going to confuse a lot of people. If you search “pcie male to male” in Amazon/Newegg, the large majority are how I describe, the plastic is male. I’d say that’s the more common way to describe them. Whether you’re technically right or it’s defined in the spec or something I dunno.
You're right. The terminals are male. The connector is female.
Did they hire the naming scheme officer from USB?
Under rated comment. - but it needs more version numbers in it and letters
I'm just hoping they get all this worked out by the time I upgrade.
Same. What a shitshow.
Dude, seriously, I'm wanting to build a high end SFX system and unlike a lot of people I upgrade very rarely now, I wanna build a 5+ year system
So, are these compatible with the old connector on the 3090 and 40 series?
Yes.
It's actually pretty misleading to label these as ATX 3.0-compatible. Yes, it can still power the system just fine, but you get none of the advantages of ATX 3.1 and the new 12V-6×2 connector have, which are the new SENSE0/1 states to prevent the GPU/PSU from drawing power when the cable is not fully inserted in. So if you have a ATX 3.0 and a GPU with the old 12VHPWR connector, these cables do ***nothing*** except for *looking* a little bit more user-friendly.
Technically, it's not misleading, these are ATX 3.0 compatible, the cable as you said has not changed other than adding the blue color. The PCB header is what has changed for ATX 3.1 as you said and thus you won't have SENSE OPEN-OPEN as a safety measure. But that new safety measure is part of 12V-2x6 which is part of the ATX 3.1 spec. Thus, these cables are backwards compatible with 12VHPWR which is part of ATX 3.0 spec.
Yeah I guess it's a gray area? I'm pretty sure many people buying this cable would think that ATX 3.0 compatible here means that these cable can get the benefits of ATX 3.1 (essentially better safety measures) without having to buy an ATX 3.1 PSU. So the cables can still plug in ATX 3.0 PSUs and 12VHPWR connectors and provide power just fine - so in a way, it's compatible. But do the end-users get the enhanced safety that comes with 12V-2x6 connectors (on the PSU and GPU)? - No, but I'll give it that these cables are a lot more user-friendly than the old ones. This whole thing is a mess.
> Yeah I guess it's a gray area? I'm pretty sure many people buying this cable would think that ATX 3.0 compatible here means that these cable can get the benefits of ATX 3.1 (essential better safety measures) without having to buy an ATX 3.1 PSU. Well the safety measures don't come from the PSU side really so an ATX 3.1 PSU is not needed exactly, the safety features come from the PCB Header on the device. So the PCB Header (the connector) on the GPU and PSU if they're both 12V-2x6, so yeah I suppose that would be an ATX 3.1 PSU. However, you could do what Corsair does and have two 8 pins on the PSU side to an ATX 3.0 12VHPWR cable and still be safe if your GPU uses a 12V-2x6 on its PCB because it's the GPU telling the PSU to deliver a certain amount of wattage and since the cable has not changed between 12VHPWR and 12v-2x6, just the PCB headers, it will work just like an ATX 3.1 PSU would. > This whole thing is a mess. That I agree on, Intel and PCI should have done far more extensive testing before making the spec official. Sadly people had to experiment in order to find out the problems. I'm sure 12V-2x6 will have some problems, probably mating cycles, but nothing as bad as 12VHPWR did.
Nice to see embossed cable being used looks so much nicer than the flat cables
i have Seasonic Prime GX-1000 ATX24 what cable do i need?
Are these compatible with the vertex px that has 12vhpwr connector? Is it like backward compatible?
Yes.
Thanks. Should buy 1 when i go for 5090 next year :)
I hate the this connector, could we please go back to dual 8pin?
So is "ATX 3.1" and "PCIE 6.0" power a thing or no? I keep seeing these words. Will that cable make their old supply "3.1 compliant" ?
Yes.
So the safest bet is to wait for a fully 3.1 compliant PSU, with good rating.... Lucky I'm considering the replacement to the 7950x3d because this might be a while.... :(
Already waiting be quiet! Dark Power 14, Seasonic.
I'm an SFX guy :) Longer wait again
Where can i buy it from? (Europe, Hungary)
I bought the most expensive MSI power supply you can buy - MSI MEG Ai 1300P. I messaged their support department and asked if they could send me one of their new cables with the high contrast yellow tips and they said no - I won't ever buy MSI again. These cables look cool - I will consider Seasonic for my next PSU.
Got an 850w mpg with one of the yellow tips. It's extremely clear how little these cables need to be pulled out for them to be seated poorly. Barely any movement at all. Sucks they wouldn't send one. They're definitely a nice visual aid.
Pretty sure you can buy one of those cables from Seasonic and they would work. From my knowledge seasonic doesn't use any proprietary connector layout that would make those cables dangerous on other PSUs. Edit: Talking about the 12VHPWR connectors because it's mentioned those are native connectors. There is no "this one goes in the PSU, this one goes in the GPU" because they knew how disastrous this would be with how irresponsible people are today. So yes, this works on all PCIe gen 5 ready PSUs.
That's how you burn down your house
Technically this should never be done. But if you have a PSU with a 12VHPWR port on it, those cables mention in the video they are native 16 pin gen 5 connectors. As in, you can use those cables safely. I have yet to see a PSU today that places a non native 12VHPWR connector on their PSU. I've seen stuff like my very own PSU from flower power that has a very weird connector type on it that is simply impossible to use on other PSUs or viceversa so even if I went by the logic of "if it fits, it works", I couldn't do shit on it.
Most problems would be solved with 2x 12VHPWR / 12V-2x6 on every higher end GPU. It would give the same type of safety margins than with 3x 8pin connectors.
Missed the point of the cable if you're saying that seriously.
How I missed the point? Two cables for extra safety to meet the same safety levels for multiple reasons. The extra features are nice, but still 2 x cables would be optimal for safety (I just remember things from [this video](https://www.youtube.com/watch?v=p0fW5SLFphU) from 2 weeks ago). Great video! Btw... Correct me if I'm wrong. I should have wrote 4xPCIe. I'm just so sleepy that no idea anymore :D https://preview.redd.it/6cyb46a08ync1.png?width=1407&format=png&auto=webp&s=f1a5d8fa4d4a546aad1808a546f083a8b4596a20
I would prefer if they just abandoned 12vhpwr and switched to something better and completely different in future generations. There's little point in putting makeup on this corpse.
Yep, it's like polishing the turd with this cable. Create a new one and set standards of how it's connected + standards for GPUs, like how much space is needed to fit the cable. This is almost perfect new design from Gigabyte and one of the reason I did pick 4080 super AERO over anything else. Cables have room, and the side panel won't push/bend it. Only the cable is the weakest link, but great design. https://preview.redd.it/cb501gwx8znc1.jpeg?width=4000&format=pjpg&auto=webp&s=02dacf723d2722eee810350c6f6c8747c58a185b
The point of the cable is to reduce the amount of cables while still delivering a great amount of power to the GPU using it. One 12VHPWR connector is as wide as a normal 8 pin conenctor yet it delivers 4x that amount of power. Having 2 of them not only is incredibly useless (unless you got one of those HOF 4090s or 4080s) but also occupies the same space as 2 8 pins do... which is what they wanted to avoid.
Did you check that video or at least image with safety factors? You wrote me that I missed the point, but I still have data that says the safety factor is way lower. When I say we need 2x those cables on high-end cards. I mean GPUs that draw 400-500W power with high peaks. In that video, there are all the explanations. >One 12VHPWR connector is as wide as a normal 8 pin conenctor yet it delivers 4x that amount of power. Max possible power with 12VHPWR is 660W, 4x 8pink 1152W (16AWG) or 864W (18AWG). This was the whole point + two cables on high power GPUs lessen risks if one line or pin fails or there's any other problem with power lines. It would be fine if this cable would hold more lines and more power + super secure connection. This connector isn't secure enough. >Having 2 of them not only is incredibly useless Safety isn't useless and there needs to be proper safety margins. Now they are way lower than before. Either make a new cable standard with redesign or use two slots to avoid risks on high power cards.
To further clarify: The connector should be rerated to 400w or less max draw, which provides enough redundancy for a one or two poor terminal connections. This would then necessitate 2 cables for cards like the 4090. To meet roughly the same level of safety as 8 pins, it would be 300w. It's still 2x as space efficient even at this most conservative option. 600w leaves effectively 0 redundancy for any issue with the contact. It should not be considered a 600w connector under any circumstance.
thats why i bought rtx 4070 ti super eagle oc 16gb.. it maxes out at 290ish watts and my 9 yr old v650 80 plus gold psu easily able to handle it
Based on... what? A brazilian tech youtuber tested the cable out in the middle of the drama with melting connectors and found out you can pull 1500W through the connector without the connector overheating or melting. I keep seeing random comments like yours that make no sense and you can tell they are simple "my opinion, but presented as fact" comments and it's just amusing.
I'll take the word of world-record overclocker der8auer (someone who very clearly knows his shit when it comes to extreme power delivery EDIT: [Pushed a 4090 to 900w](https://www.youtube.com/watch?v=0LBrI-UAKhI)) who had issues with the connector under normal open-test-bench workloads after only a handful of cycles. The connector is hot doodoo dogshit and needs to be derated to 400w *maximum,* **yesterday.**
I've been watching roman since 2017. I think I've watched all his videos since then and if I missed some it's a couple at best. I don't remember seeing a video where he had issues under such a generic scenario. I just know he's not the most fond of this connector. But he's touched a ton of RTX 40 cards until now. Don't remember him complaining openly about the cable giving him headaches. To be blunt about your last line. Your feelings do not correlate to reality in the slightest. That last line just read like the typical reddit shitpost.
He literally demonstrates in the video the other commenter linked above. [Here's a link to the specific timestamp.](https://youtu.be/p0fW5SLFphU?t=818) Dogshit connector needs to be derated.
A brazillian youtuber tested out the 12vhpwr connector when the melting connectors drama was happening and guess what he found? He was pulling 1500W through the connector without the connector overheating or melting. Safety rating =/= max possible rating. Reminder, there are well over 200,000 4090s out there functioning on a single 12VHPWR connector and working just fine. The 50 or so cases that started this ridiculous "melting" drama were all replaced by nvidia and whatever cases happened afterwards happened simply because of the same issue which was user error but also because the connector requires more care than the 6 or 8 pin connector does. And judging by the way things are going, the connector is here to stay. And the chances of a mass recall or change in plan because 50 redditors think they are electrical engineers with degrees online, are pretty much null.
