ATX12VO: Future Power Supplies will not have 24-pins ATX connector anymore, but 10-pins
Over the years to come there might be an interesting move in the power supply industry. Intel is hard at work on a new PSU standard, purely based on 12 Volts. That would mean a power supply with just a 10-pin ATX connector and a primary voltage of 12Volts.
Admittedly, we'd not be opposed to the idea as it could help with efficiency but also cheaper power supplies. Currently, power supplies have 3.3 5 and 12 Volts, but most of your PC is consuming at that 12 Volt feed, your graphics card and processor for example. Then typically two rails are added to provide 3.3 volts and 5 Volts towards a USB drives, HDD or SSDs.
A new standard is developed by Intel, it is called ATX12VO and as you have guessed by now, it will only offer a 12 volts connection. So doesn't that pose a big issue with the compatibility of 5V devices like your SSD? Well no, because future motherboards will then become responsible for converting 12 volts to other required voltages through DC-DC conversion. How that would work out cables wise remains a bit of a question though.
Such a power supply would need much fewer wires on that ATX motherboard connector, and as such ATX12VO only has 10 cables at that specific connector. Of course, there will be PEG connectors, etc for say your graphics card leading from the PSUs, but really all cables coming from that PSU would be 12v based.
The new standard will be implemented in the industry first, and it might take many years before it'll hit the consumer market. Intel will release the ATX12VO specification this year. At CES the prototypes already have been shown. You can read up on the new spec right here.

ive imagined going full DC after eventually getting enough solar panels and batteries, so like 12v wall outlets, and wondered about what to do with my pc and its complicated PSU, now i see thats probably getting addressed later on, and eventually everything will run on usbc, that means almost every device will accept 12v power through it, pretty cool, no more dc>ac>dc

Actually, it would have been precisely the perfect time to get rid of it, to replace it with a more handy connector, instead of adding more wires to it.
Original ATX spec was only 20pin. We didn't move to the 24pin connector until 2004 with the ATX 2.2 spec. Not quite "decades old" yet....and 10 years ago there was little reason to do away with it, as the ATX2.2 spec was still relatively new. 20 years ago, we were using a 20 pin connector...

While you are totally right in your prediction of the future, I'm convinced as well this will happen eventually, the world is far from ready.
First of all, local (in the house itself) energy production and storage is still basically non-existent.
Yes there are tons of houses with solar panels on them, but if you look at the total number of homes in the world and how many of them have solar/wind directly connected to them... the percentage is microscopic... like 0.0001%
There are entire cities in poorer countries, hundreds of thousands of people in them, and not a single solar panel in sight. They do have a few smokey coal plants though...

So, come back 50 years from now and there will probably be 12v or 24v outlets in the wall, at least in the "1st world" with the possibility of plugging electronics straight to them with only DC-DC conversion. But I personally think I'll be inside a nice colorful urn by that time...
