Find real low power consumption for rack board ?

Hi experts,

I was just wondering...

Except for Data Centers which always need more ...

What about non-cloud infrastructures. Who don't need enormous power.

If one of the goals to be achieved by our processors is to reduce power consumption. Why do case and motherboard manufacturers not adapt their offers on racks that can accommodate lightweight processors?

At what I still see the same type of power supply mounted on the motherboards :(.

Have you some infos about special racks boards for them ?
