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.

I have seen this all ready on prebuilt from Fujitsu and Dell, maybe this is not new at all, just not a standard.

Looks good to me. The old, humongous connector doesn't fit this decade anymore. In fact it should have disppeared 10 or 20 years ago already. It's ridiculous that thing is used for nothing but to deliver power to the mobo, and not even all of it these days because the CPU got its power elsewhere. You'd think a couple of those wires could at least be used for communicating with the PSU for monitoring info, not just for the power on status, but nah.

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...

In industrial PC most motherboard supplie the 3.3v and the 5v, PSU are already only in 12v (because it is one of the standard ).
The bad thing is that yes, motherboard are generaly more expensive.
As a lot of Intel's "improvement" it will work Only if people adopt it... I don't think it is already won...
Anyway, adaptator will exist, i still have a PSU with 20pin and only molex that still work with 24pin and SATA adaptators for my spark/injector program.
