It's happening again, melting 12v high pwr connectors

Corsair officially reacted to the JayzTwoCents Video on Reddit:

bold move with those words, i hope no one proves them wrong anytime soon, that would be terrible

 

[Endymio]

They don't make the connector by themselfs, no, but they do entirely decide on what connectors to use on their gpu's !

No, they decide on the connector standard. Learn the difference.

And they chose to go from a completely safe design, to what is a fire hazard

Stop the gaslighting. No fires have occurred. And, as Corsair itself says:

"we have yet to see an undamaged Corsair 12V-2x6 cable fail, and we sell millions of power supplies, no exaggeration....."

Get an in-spec cable and don't damage it. You'll be just fine.

I guess the cables get a bit of heat damage when they burn, so he is technically never wrong.

We haven't seen any 12v-2x6 fail, neither damaged or undamaged ones. All failed cables are old 12vhpwr ones.

Funny, derbuers corsair cable is 2x6...

Lol what - so you are saying it was not nvidias choice to go from 8 pin pice to 12 pin ? Nvidia fanboy trying to twist the narrative..

The cables did not change from 12VHPWR to 12V-2x6, just the sockets at both GPUs and PSUs.

If plastic melts at 250c, it's a fire hazard. That's above the flash point of the paper the receipt for your 5090 GPU was printed on.

So, no gas lighting. No gas needed.

It's a fire hazard.

I will be curious to see when we start routing a separate AC power plug in to our PCs.

he just proved the problem is the card, it should not allow that to happen even if there is something out of spec in the cable.

Issue is both card doing no load balancing, and connector / cable being woefully underspecced for it to have a reasonable safety margin - it shouldnt be rated for more than 300w tops.

If a manufacturer changes the name of the cable, does it change its construction?

Here's from Corsair:

 

[JustBenching]

We should go back to 8-pin cables so we can see if they start failing. Certainly the defects and tired workers only work at the 12-pin cable factories. Or, is it that the cable is not robust, pushed to the limit, and ANY mistake ANYWHERE will cause them to fail?

If you try pushing 700w out of an 8 pin cable it will fail, no question about it.

 

[Dragam1337]

If you try pushing 700w out of an 8 pin cable it will fail, no question about it.

Yeah, cause we would just be using a single 8 pin /facepalm

 

[Bomby569]

that's absolutely true, but you need to have some hardware level checks on the card, a cable is just a cable and anything can go wrong and will go wrong if you let it.
Even toasters have safety mechanisms.

AMD managed to run 8-pin SEVERELY out of spec with their 295X2. 550W out of TWO 8-pin PEG connectors.
Assuming a perfectly balanced load and that 75W out of those 550 came from the PCIe slot, that's still more than 230W pulled from each connector rated for 150W, so a little over 50% above what it should handle.

Try doing it with 12V-2x6 and the result will be one only: melting.

 

[JustBenching]

Exactly my point? The 12vh is much more robust than any 8pin, the problem (if there is a problem) is that they are only using 1.

Pushing 550w out of 2 12vh? That should be trivial.

I am in complete agreement. So now, who is to blame for designing such power hogs drawing from a single connector which isn't keeping up?

I don't care cause I don't think it's an issue. I'm still on an original 12vh and everything is fine.

The point I'm making is that complaining about how bad the cable is is just crazy, since it can handle way more power than any 8pins.

But to answer your question, aibs are to blame. They chose to use only 1 connector. Hof uses 2.

Got my Seasonic Prime TX 1600 WATT ATX3.1 a month ago , has two 12v 2x6 connectors' and cables , but never had issues even with a 1200watt ATX 3.0 , since two years ago , but wasn't about to use it for a 5090 , and I have WireView to check how much amps are uses, plus a clamp meter to check for distribution per wire ,small price compare to spending over 2K a GPU , mitigation , not foolproof !

No, it is not alot more robust - in fact it is the exact oppersite. 12 pin is close to unusable after just 5 replugs, and extremely prone to user error, due to it being super finicky. It is rated for more watts, but it really shouldn't be.

Using 2x 12 pin would not fix the fact that there is no load balancing of the power on the gpu - all power could still come from a single wire.

It can handle more than 8 pins, yes. But I personally don't believe in 600W being safe. 300W rating? Now that's a point where I'd be able to trust it.

And how is not NV to blame? The first cards to have issues are always the FEs. And if they themselves used two VH connectors and mandated every AIB to also do so, there'd be no issue here.

Really? Unusable after 5 replugs? I have repliged it like 10s of times but sure, whatever.

As I've said regardless of who you wanna blame, 12vh > 8 pins in every conceivable way. People should be complaining that they only put 1 of them in the gpus instead of complaining about the cable itself.

The connection becomes DRASTICALLY worse after replugging just a couple of times, due to the connection relying on tight pressure to make the connection on the tiiiiny connection surface.
