Question Task Manager -- "Power Usage is Very High" ?

if the apps in question are all games, it sort of makes sense as they using a bunch of different parts in PC, and windows calculates how much they are using.

The new feature will allow you to view the current power usage on a per-app basis. As well as monitor the system resources an app takes up over time. For example, it uses the disk, processor, and graphics usage on each app and processes to calculate the overall energy impact on your system.
The Power usage column displays how much power the app or service is drawing in real-time.

on a desktop PC, I wouldn't worry too much about that row. Expect its more helpful on laptops running off battery.
