I don’t think the 25W ECO mode would actually limit power consumption because it would lengthen process execution time. It would primarily limit the processor’s computing power, preventing it from overheating if it’s not needed (for example, for small, non-urgent tasks to be performed overnight).
I would not be a big fan of the choice of power modes. 160W is beyond what the stock cooling solution can reasonably handle. This makes only sense when you are creating a custom cooling solution with custom machined cold plate and for that extreme overclocking you’d want to use ryzenadj anyway because you would really want to undervolt as well.
Those power setting choices also miss entirely the most interesting range of 80-100W. 100W is where you get almost the same performance as with even 140W, while 80W has the best balance of power to performance (at maybe ~ 10% performance loss) in my opinion.
