Controversy surrounding the GeForce RTX 5090, a $1,999 GPU based on NVIDIA's "Blackwell" architecture that some early adopters say is so powerful that it can burn houses down, is totally overblown, according to a tweet that Falcon Northwest published to its official X account today, one where the PC integrator says it hasn't seen anything similar to what overclocker Roman Hartung (der8auer) had described as being "extremely concerning" in a video that he published to his YouTube channel yesterday (i.e., a GeForce RTX 5090 power cable overheating beyond 150 degrees Celsius).

It's great that MODDIY put out their statement but a very big detail was left out and something that has been spoken about in some threads and it too relates to the difference between 12VHPWR vs 12V-2x6 and that is ATX 3.0 vs ATX 3.1. Now I welcome our experts to chime in on this but I believe that 3.0 was 12VHPWR and swapping cables doesn't just upgrade it's sense pins.

Der8auer clearly indicated that an older ASUS Loki ATX 3.0 PSU was used with the melted cable so . . .

and that being said users with older PSUs upgrading their cable seems like an odd way to avoid this.

The only specification change with 12V 2x6 was on the PSU-side and GPU-side. The sense pins were shortened and the power pins were lengthened.

Cable specification did not change.

Why MODDIY is recommending people upgrade to what should be the 'same' cable seems suspicious. I mean they say it's specs are the same but they 'improved it'.

They could just say how it is improved. It's not like people can't just cut open the cables and compare them.
 
From shunt resisters being used by AIB partners to statements by users in other forums about NVIDIA removing hardware present on the 3090/3090 Ti cards (which 1st introduced the 12VHPWR connector to NV's cards), there's more details coming out that the current RTX 50 Founders Edition cards could use improvements.
 
How does one mix things? So an old cable plugs into the updated socket but shouldnt?
 
So they changed the cable just enough so people can't use the one they already had? Awesome

They changed the plug on the card/PSU side, but they didn't change the cable. Which is the odd thing here.

So, in theory, having an old cable ~shouldn't~ matter. Provided it's actually at spec. And the spec is adequate (which is the part I and many others have been questioning all along).
 
Even looking at J2C's videos... if you're going with a new GEN 5000 series.. I would get a PS of the most current spec and make it a good one that supports the 3.1 power delivery. Those cables SEEM to be ok.

Just what I've gleamed from the cube so far. (Yea.. that old of a skater movie reference... sue me. )

I would agree, if you are going to drop that kind of money on a GPU, getting a brand spankin' new PSU to go with it is chump change and cheap insurance....
