be quiet! Introduces 12VHPWR Adapter Cable for RTX 4090 and RTX 4080 Graphics Cards
be quiet!, the German manufacturer for premium PC components, is today releasing its 12VHPWR 12+4-pin adapter cable for ATX 2.X-compliant be quiet! power supplies. This cable offers an alternative to bulky and short standard adapters that come with next-generation graphics cards like NVIDIA's GeForce RTX 4090 and 4080 models. It features an elegant black sleeve and connects two be quiet! PCI-Express 12-pin sockets on compatible be quiet! power supplies for a maximum power throughput of up to 600 watts.
While the 12VHPWR adapter cable works with all current, modular be quiet! power supplies that have at least two be quiet! PCI-Express sockets, users are still advised to check power recommendations of the graphics card manufacturer. A general recommendation for the new Founders Edition cards from NVIDIA can be found below. To prepare for future GPU launches, be quiet! is also working on ATX 3.0 compatible power supplies. Dark Power 13 is scheduled for launch in early 2023, with Dark Power Pro 13 following a bit later. Other power supply series in the be quiet! portfolio will be reworked for ATX 3.0 compatibility in the near future as well.
The 12VHPWR cable is as of today available for purchase at a recommended retail price of €19.90 / $16.90 / £16.99.

Wonder if some one make a 4 to 1 model
There is no communication happening it's just a ground or open on those pins. What GN showed was just simply that leaving one of the adapter 8 pins not connected only grounds one of the sense pins and the card doesn't pull 600w.
I don't understand how PC community is so into electronics, but can't be bothered to do some reading on the literature provided...
EDIT: Now that I looked at the photos more clearly it's 12+12 pins on the power supply side, so that's absolutely not any standard.
in fact one of the reasons the nVidia 4-to-1 adapter has so many connectors is to ensure that you end up using multiple lines
Some Reference specced (450w) AIB's are shipping with 3-to-1s,would be interesting to see whether they can still be set to >100% Power Target by switching to a 600w cable
triple 8 pins should still unlock 600 W, it doesn't quite make sense. And one can have molex to 6 pin to 8 pin adapters for all we know.
So you could end up having 300,450 and 600 W by only plugging 2 by 8 pins depending on which ones.
In Corsair's own cable all I see is dual 6 pin with sense pins grounded internally somehow. I see no sensing cables attached. How about that. GN will be left bamboozled by the sheer simplicity.

They are all standardized (connectors and pin outs) on the PC component side (motherboard, GPU, SATA, Molex, etc.).
Corsair will have to come up with their own cables.
They have their new power supply that comes with a proper cable www.silverstonetek.com/en/product/info/power-supplies/HELA850RPlatinum/ so I'm guessing you need to wait a bit for them to make a different one for older units.
