Can I power Nano via 5v pin?

Hi guys,
I recently brought a Arduino Nano v3.0 and am confused if I can power it via 5v pin or not. I'm following a tutorial here and want to know if I can power my Nano via 5v pin as shown in the tutorial.


You can power it via 5V pin IF your power supply is 5V and is regulated.
