How to power STM32F411E-Discovery with external 5V?

Im using STM32F411E-Discovery (MB1115D) for my project and i need to power it from an external supply instead of USB. I have a external 5V supply but not sure how plug it in, should i inject 5V directly into 5V pin and ground to GND on 25x2 header?

Yes, looks so.

UM1842 does not say anything different. Connect +5V and GND and it should run.
