Here's some information—my cable is about 10 months old.
Here are two tests at different power levels to show you the temperatures:

I'm not sure what this means because I've never measured wire/contact temperatures on even the old connectors.

However, I've been running a test overnight on my pair of Titan XPs. They are out on the bench but have been operating at nearly max power (230W) for 20 hours. I stuck a thermocouple into each power wire socket and got readings from 38C to 44C.

These are blower cards, so its hard to say how much of that temp is from any resistance versus being heated up by the card itself.

Begs the question, if a 230W load can get a connector pin to 44C, how hot would it get at a load that is over twice that?
 
My Alpha is showing temperatures that are slightly higher than normal, so if the cable were new, the temperatures would be 3–6 °C lower. But yes, when the cable starts showing 60–65 °C, I’ll replace it. Lian Li power supplies come with one 12-to-12-pin cable and one 2x8-to-12-pin cable, which is handy as a backup; after that, I’ll probably buy something else.
 
Anyone here in possession of a wire view pro interested in an experiment? Are you seeing uneven power distribution on any of your 6 power pins via the wire view pro? This experiment might be a permanent solution to the 12VHPWR connector deterioration problem . I have been wanting to experiment with a connector longevity enhancement product I've been using in automotive applications for over 20 years. The product is called Stabilant 22. It's fully endorsed by Volkswagen Auto Group and has proven extremely reliable in preventing connector meltdown in high power automotive 12V. circuits like HVAC blower motor connctors and circuits with 10-15 amp loads that are consistently exposed to vibration and damp/corrosive environments. You already have the wire view device to monitor the situation but no permanent solution other than the connector revolving door replacement. This is a perfect opportunity to test the product free of charge as it's quite expensive (I'll ship it to you for the testing) and use wire your view data to determine it's effectiveness. I've attached a portion of a PDF describing some of the high power application uses in the automotive realm for you to view. Stabilant 22 is also widely used in the aircraft industry for critical avionics device connectors to prevent signal jitter caused by vibration and fretting corrosion. Pilots tend to get very nervous when altimeter readings fluctuate rapidly from poor wiring connector signal transmission. Any way I just received a new 15ml bottle and I'm wondering if anyone is interested in trying it on you 12VHPWR connector. Here is a short video describing it as well. Let me know if your interested.

Another AIB denying a warranty claim? I'm shocked. SHOCKED!

Well, not that shocked. Apparently it's a 2 year minimum warranty in that country, yet they still denied it.

Your card is FE correct? That requires a wire view pro 2 wired to get into the angled and recessed connector. No worries I can do the testing myself with my FE card but I won't be doing it for a while since a rather large unexpected expense (vehicle replacement) recently hit me financially and car payment interest is not something I'm willing to do.
 
"Some of you may have seen the remote mounted dual 8 Pin auxiliary module I posted. Well, this is the direct mount Quad. Current per conductor is almost perfectly halved when compared to the native 12V-2x8, along with a dramatic reduction in wire temperature.

Sense pins are set to 600W. It can be used in conjunction with the 12VHPWR or completely standalone, and has been tested up to 800W with a shunt mod. We're shooting some videos now going over installation, live temperature and current data, as well as a 24 hour sustained load.

We are also working on custom backplates that will make the modification look more OEM and integrated.

This isn't limited to just the 5090 or any particular brand. We have models going into production for nearly every card including Founders Edition."

Niice looking and functional long term. Will there be an FE version? Never mind last sentence states FE as well.

If Palit officially sells their products in EU then they have to respect the warranty policies of that country. Wether it happens via the official retailer where it was bought from or customer directly handles it with Palit (or their importing company), it doesn't matter.

No, the vendor (shop) were you bought the hardware needs to to that.
I live in the EU, you should read this link and stop posting false info:
https://europa.eu/youreurope/citizens/consumers/shopping/guarantees/faq/index_en.htm
The 2-year legal guarantee applies to your contract with the seller, not the manufacturer (no matter where they are located in the EU). As part of the contract, you might have an additional guarantee, called a commercial guarantee, which might offer additional benefits that go beyond the standard 2-year legal guarantee. However, the commercial guarantee does not replace the legal guarantee.

As far as I know, the manufacturer warranty cannot be worse than the sellers guarantee, it can only add to it. There are also a bunch of what-if scenarios, like if the shop where the item was bought goes under within the warranty period, the warranty matters move to the manufacturer So that the buyer isn't left without protection, and if the manufacturer offers warranty repair services within your area then the buyer can bypass the seller and deal with the manufacturer directly, which is what happened here and so on.

how bad is this, and how do i fix the current imbalance?

IMHO, don't fix it.

I don't think that looks bad at all and if those are contact temps, they are actually similar to what I measured on the 6 power contacts of the old school PCIe 8 and PCIe 6 connectors on my Titan Xp loaded to ~230W, the max one was about 43C. The 12VHPWR does have a higher spec for contacts, 600W across six pins, so 8.33A per pin. A PCIe connector has 3 pins rated at 150W, 4.16A per pin. Also note heat from the video card itself will warm the pins.

The per wire current variation is considerably better than der8auer's example where one was at 23A. I don't think load balancing would actually improve that much, if at all.

Current imbalance will be the leading indicator - I would watch that like a hawk and have a pretty tight tolerance on its variation. It is established by your exact power supply wiring and its connection to your specific video card. It really should not change. It is unlikely to get better on its own, if it changes it will be worse.

Also, it may be obvious, don't disconnect and reconnect unless you absolutely have to. I don't think it is bad enough to put more connection cycles on your gear in the hope of getting a better match. Leave it alone and monitor. Automate the monitoring, ideally have a warning for a minor deviation and automated shutdown for something bigger.

“Super Flower's 12V-2x6 OCP Dongle Watches Every Pin, Blacks Out Your Screen on Overcurrent​

by DrUsmanSaleem Today, 20:04 Discuss (0 Comments)
Super Flower has launched the VGA 12+4PIN OCP Dongle, a small inline box that sits between the PSU cable and a graphics card's 12V-2x6 connector and keeps an eye on the current running through each 12 V line. It was first shown at Computex 2026, and can now be seen on Super Flower's website, priced at NT$1,190 (roughly $38) in Taiwan. However, you can't buy it on its own just yet. For now, it's only offered as part of a limited promotional bundle with Leadex VIII power supplies, and there's no word on standalone sales or a wider release.

As for the protection part, each alert needs to hold for 10 seconds before it fires. Between 9.5 A and 12 A on any line, or if two lines drift more than 6 A apart, the LED turns orange and the buzzer starts beeping. Past 12 A, it flashes red with a continuous tone for 180 seconds, stays solid red for another 15, and then triggers "VGA Black Screen Protection." That mode stays active even if the current settles. Super Flower doesn't say how the black screen works or whether power is cut, and simply advises shutting down and checking the cables. That part can be a bit unreliable, but it's safe to assume that most users will suspect something is wrong if the screen blacks out for a significant bit of time.“

9.2 amps is technically within the 9.5 amp spec. Unfortunately, I think the only way to get better balancing is to use to play lottery with different cables.

If the WireView 2 Pro is screaming at you like mine was for the current imbalance, replace the power cable if reseating both ends doesn't fix it.

Also, if you read Thermal Grizzly's warranty info, adjusting the current imbalance alarm more than the default 40% will void their 2 year warranty. So don't go doing that to silence the alarm.

If it's not alarming on you, I wouldn't sweat it. You'll know when it does.

Frankly, I won't bother because the whole discussion is irrelevant and alll this time you sound like you are just picking a fight. What is even the point you are trying to make here as Palit themselves offer 3 year manufacturer warranty?

I still would just keep an eye on it. The power feed to the card is dynamic, it will change with load. Also, watch the balance - did the other pins go up as well? Watch all six, not just one.

If a pin really goes south, it will be obvious.

So you had no point and are just picking a fight, got it. Any way, in some cases, yes. Like I read the article wrong when it actually said that the manufacturer warranty cannot MAKE the seller guarantee worse, it is just a service that is added on top of it. Bit of dyslexy from my part. But I also got an impression that while manufacturer can set their own RMA terms, it has to be set before the sale and they cannot change them arbitrarily during the warranty period of already sold products to deny repairs. It is a legally binding contract basically. So when was the "we will not fix the burnt 16 pin connectors" added to the terms?

No I am not, I am referring to the rather arrogant if not hostile way you correct the said false information. My whole point was that Palit is in the wrong here and the guy should contact what ever customer rights representation they have in Sweden and sue with their help. Instead you derail it to clashing sabers about semantics and finer differences between sales guarantee and manufacturer warranty, which I do not give two shits about and neither has any relevance with the issue at hand: Palit very likely doing something illegal.
 
The 2 year EU rule is a minimum because some manufacturers were trying to get away with 1 year or less.

If the manufacturer offers more than 2 years at the time of purchase they have to honour it though, it's not rocket science - thus Palit is 100% in the wrong.

Many vendors explicitly tell you to contact the manufacturer directly, that's not illegal - there can be plenty of good reasons too.

My Seasonic PSU from Amazon France (not a third party seller) failed after 1 year and they told me to contact Seasonic directly to get the smoothest RMA experience. I have done my faire share of RMAs here in Europe (I live here) and whether the vendor handles it for me or the manufacturer, varies a lot. Vendors have never screwed me over though (far too risky for them), but some manufacturers like Asus certainly have (or tried to).

The 5090 isn't that old of a product anyway so it cannot be out of warranty when legally purchased in most countries so there is certainly grounds to fight on.
