Ever since the first rumors in July 2020 about NVIDIA adopting a new power connector for its GeForce RTX 30 Series graphics cards, many have had questions about it. It was immediately recognized by some that the connector resembled an as-of-yet officially unannounced PCIe Gen 5 12-pin Molex Micro-Fit series. Then in November 2021, early images of the forthcoming ASUS ROG THOR Platinum II PSU showed it including an adapter with 2x 8-pin connectors on one side and a 12-pin on the other. It has now been confirmed that the PCIe Gen 5 power connector is indeed compatible with...

Having three eight-pin 150w cables running to my GPU, for 450w total from the PSU, a single 12-pin 600w cable would certainly be nice.

I wound up buying nicer cables to replace the ones that came with this Corsair AX850 as the 'pigtails' on each one made them difficult to route and manage!
 
At first, I was skeptical about the new 12-pin but now I'm on board with it after reading so much on it. Here's hoping more AIB partners begin adopting it. It would be nice if when I do my next build if I could cut down on some of the cables as it is getting a little crazy with the 3x 8-pins I've had to use for various Ampere and Turing cards.

Three goals for the next build are, moving up to something like a 5950X/12900K with a 360mm or 480mm AIO, 12-pin PSU/GPU combo, and exclusively having NVMe drives in/on the motherboard. Not planning on anything for a year or so but that's the direction I'd like to head in and more than likely be powerful enough to be my last build to last into retirement. Granted by then it could become standard for 2x 12-pin connectors but that would still be better than 3,4, or more, 8-pins.
 
I'm somewhat surprised we haven't seen a boost to the power provide by a PCI slot yet. 75W is a good deal of power for most things, but given that power augmentation has become larger and more common, I'm still surprised we haven't seen a bump there.

Granted, it would cost a lot more to add it to a motherboard than it does external cables. I don't think you need to go crazy and jump to 600W+, but a bump to like 150W would get graphics cards back in the realm of being no-cable while still providing good performance, rather than being relegated to mostly on-par with IGP or highly customized AIBs with crazy price tags to go with it.
