An interesting development has been spotted. The ATX12VO power standard is somewhat new yet coming and can help out in increased efficiency for desktop power supplies. The standard does require a compatible motherboard with a 10-pin power connector and compatible power supply, which only features a 12 V rail.

So if released, the adoption rate will be slow as there then would be two standards. The main difference being That any voltage conversion different from 12V will be performed directly by the motherboard. So, on the one hand, you get a very simplified energy-efficient power supply that roots only 12V, and on the other hand, you'll see a far more complex motherboard when components that differ from 12V are required.

From the looks of things, Intel is interested in softly evangelizing the standard, Starting with next-gen 600-series motherboards that will be the infrastructure for Alder Lake-S processors. We think this solution will find its way to entry-level products and system builders first. The current design PSUs will be here for many, many years.
