ATX12VO Power Supply Standard gets tested, shows really good IDLE power consumption
We've talked about the new ATX power supply connector for motherboards a couple of times already. But a production model has been tested by our German colleagues from Heise, and it shows promising results.
A while ago Intel already announced that it is working on a new standard for PC power supplies. ATX12VO 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.
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.
The German tech publication Heise has been given the opportunity to test an atx12vo system and saw notable steps in overall efficiency.
ATX12VO overall system uses less than 7 watts
Intel provided Heise with an early series LGA1200 motherboard Asrock Z490 Phantom Gaming 4SR and a power supply HP1-P650GD-F12S with ATX12VO technology. Even with the BIOS standard settings, the system with a Core i9-10900K, a SATA SSD and 16 GB of RAM achieved a power consumption of only 13 watts when the Windows desktop was idle. Only a few (current) ATX boards can do this and only with optimized CPU energy-saving settings.
With activated C-states and activated SATA and PCIe Link Power Management, they were able to reduce the idle value of the ATX12VO test system to below 7 watts. initially, there will be mainly complete systems from large PC manufacturers with ATX12VO technology. In the longer term, the new standard will also be of interest to PC hobbyists, because Intel works with power supply manufacturers such as Channel Well, Cooler Master, Corsair, Delta, FSP, High Power and SeaSonic.

Isn't the CPU using the 3.3v/5v line too?
If not, then i agree there isn't much to use there. maybe something around the sound card or the nvme
The majority of current is already being consumed in 12V today. The relatively small consumers in other voltages won't require massive effort for power conversion.

See the system still needs 3v and 5v to be operational. This new "standard" does not magically negate the need for 3v and 5v. This just moves the conversion to happen on the motherboard now. Which is both good and bad. Good that it reduces the wires from PSU to motherboard, and reduces the cost of PSU slightly, but now you are paying for the conversion cost on the motherboard, so motherboard costs go up by the same margin. This means that rather than paying for 3v and 5v conversion once in the PSU, we will be paying for it in every new motherboard.
What do you replace more, motherboard or PSU?
In my case, my PSU has lasted me 3 motherboard generations and is still going strong, so I paid for 3v and 5v conversion only once, rather than paying for it 3 times over. IMHO, this only benefits the OEMs who don't produce the upgradeable systems to start with, and now they are able to reduce wires as well.
Pick your poison, pay for 3v and 5v conversion once, or every time with new motherboard.
EDIT: Grammar

Look at who is pushing this "standard", the same people that require you to upgrade your MOBO every generation anyways. They are probably setting it up for some form of reimbursement from the motherboard and PSU manufacturers.
Personally I would prefer it to say the way it is so I can build as large or as small of a system that I choose. Not be limited by how much conversion capability the MOBO has for storage connections.

lol, like we'll see any of those cost reduction benefits. PSU makers will just pocket that. At the end of the day, it will be just more expensive motherboards.
Cheaper PSU's incoming then.
