Intel Encourages Adoption of ATX12VO Standard on Alder Lake-S Motherboards
The ATX12VO power standard is a new specification for desktop power supplies which boasts greatly increased efficiency over regular desktop power supplies. The new standard requires a compatible motherboard with a 10-pin power connector along with a compatible power supply which only features 12 V rails. The standard requires that any voltage conversion above or below 12 V must be performed directly on the motherboard which increases the complexity and cost for motherboard manufacturers. Intel is interested in promoting the standard with their upcoming 600-series motherboards for Alder Lake-S however most enthusiast boards are unlikely to feature the standard. The standard may find higher adoption with entry-level motherboards for system integrators and pre-built suppliers who need to meet strict government power efficiency regulations.

New motherboards have to be made anyway regardless of what the end up using.
New psu's for oem builds, again not sure how it would be a problem
For motherboard, especially on Intel platform where people have to change board every 2 gen, increasing the cost of motherboard is just moronic.
And the difference in power saving at idle is only a few watts even if efficiency improve by 20%
Classic Intel - stupid inside
Intel isn't pushing this for their advantage, they're pushing this because it's a good thing for everyone. Whether you like Intel or not, this is something everyone should get behind.
This change does require a bit of effort on the psu manufacturers side regarding adjusting the internals but that won't be affected by any shortages really.
So personally I still see no issue with releasing anything like this at this time
If anything this should decrease the cost of motherboards and increase the cost of psus
(EDIT, got this ^ indeed backwards, my bad, ignore that part)
This is an all win situation for everyone. Intel has no stake in the design, it's completely an open standard. I hope that didn't seem like an attack. I only wanted to help with the understanding that this is a very positive change for the industry. It's a change this is both logical from a design perspective, but also a cost perspective. More efficient and less expensive equals a win for everyone.
the mobo will be hotter as it will convert high amp 12v to high amp 5v and all other voltages.....cooling it will be more complex and what you save with psu (if will be cheaper?) you will spend on mobo and connectors..
is more like re-inventing the wheel by making it more complex but in the end with the same functionality and costs...
Nowadays less and less components uses 5V and 3,3V, and power requirement for those are really low, and i get that transition to 12V has started more than 10 years ago, but still i'm not confident of having increasing power on motherboards. If it is a matter of efficiency, we need now to measure a mobo efficiency too.
As for cooling, the PSU has a dedicated cooling fan, IDK of any case that focus on cooling around the motherboard power connectors.
20 W its a nuc ....
old psu golds v550 cooler master :
efficiency 86 % at 40 W 90 % at 60 W
All this does is moving parts of the PSU on to the motherboard.
Now instead of PSU makers having to achieve higher efficiency, the ball is just passed down to the Motherboard.
Unless of course they go full Atom & subsidize these parts :D
This might increase requirements for the existing VRM designs (and hence cost to some extent), but that's about it.
Most of the auxillary voltages on mobos are regulated by cheap buck converts with little regard to efficiency / ripple suppression etc.
