The system needs power to run - that is correct.
However, a power plan is something different in that power is reduced in some manner when a component is not in use.

Open the Command prompt with admin rights.
Run "powercfg /list" (without quotes) and post (you can use Copy and Paste) the full results.
Here is what the results look like on my computer:
C:\Windows\System32>powercfg /list

No customizations of any sort.
