The updated 12V-2x6 connector, the follow-up to the controversial 12VHPWR connector has passed a series of stress tests with flying colors. HardwareBusters took the new connector to task by not only using it under ideal settings, but also tried a couple of "user" error-type scenarios, and the updated 12V-2x6 connector performed flawlessly. From bending the cable beyond the recommended level to only partially inserting the connector testing showed it maintained an average temperature between 41°C-46.5°C, even when under load with 640W of power. Since testing was performed by using a load tester the sense pins did not restrict power from the PSU. The connector also passed testing, via proper insertion, with 660W of power.

That's good to hear. So when the 5000 gen of cards from Nvidia comes out we will have a more reliable connector!
 
Yep, my only concern with this testing is the quality of cables used with the connector. What they had looked pretty beefy and I'm not so sure if all manufacturers will use something similar. Otherwise, at least its progress.
 
I think this ship has sailed, nothing will rebuild my confidence in this type of connector. They should stop beating a dead horse and design a beefier one.

t’s essential to remember that every power cable and connector carries some risk of failure, and no design is entirely flawless.”

Oh, really? Then why did I never hear about traditional 8 pin and 6 pin connectors melting in droves?

Did you look at your own link? Because using this search term shows more images of melted HPWR cables than 6 and 8 pin PCIE connectors. Actually of the latter I see zero on the first page, maybe there is one but I think that's a modular PSU connector.

BTW old 4 pin molex cables indeed were capable of melting due to bad connection, but they were never designed to transmit high wattage. This is why the 6 pin PCIE connectors replaced them on video cards. The 12HPWR had one job, and it failed miserably right out the gate.

I agree, but honestly never had a problem with my connector on either of the 4090's I've owned. There is always room for improvement on anything manufactured.

This is probably because I just linked a google search, and those aren't static pages. It's going to show search results based on your own Google profile...

My mistake. I should have taken a screen shot. It was full of gooey plastic goodness.
