2 - Click on the OU where the computer account will be added, right click and select Delegate Control.
3 - Add the user on the list and select next
4 - Select a custom task to delegate, select next
5 - Select Computer Objects from the list of objects and next.
6 - Check for the below noted permissions and properties.

If the computer does not exist then the only right required is "Create Computer Object" If you are joining in User Personality Mode (UPM) mode you will also need the right of "Write preferredOU".
