Just to reiterate more information about this topic:
Jonny Guru, regarding DeBauer's Video:
If it was that hot, he wouldn't be able to hold it in his hand. I don't know what his IR camera was measuring, but as Aris pointed out.... that wire would've melted. I've melted wires with a lot less current than that.
Also, the fact that the temperature at the PSU is hotter than the GPU is completely backwards from everything I've ever tested. And I've tested a lot. Right now I have a 5090 running Furmark 2 for an hour so far and I have 46.5°C at the PSU and 64.2°C at the GPU in a 30°C room. The card is using 575.7W on average.
Derau8er is smart. Hr'll figure things out sooner than later. I just think his video was too quick and dirty. Proper testing would be to move those connectors around the PSU interface. Unplug and replug and try again. Try another cable. At the very least, take all measurements at least twice. He's got everyone in an uproar and it's really all for nothing. Not saying there is no problem. I personally don't
like the connector, but we don't have enough information right now and shouldn't be basing assumptions on some third party cable from some Hong Kong outfit.
Falcon Northwest has put together and tested a ton of 5090 systems and haven't seen anything like what DeBauer is showing either:
