Power arduino from switching power supply

Hello,

I'm thinking of buying this power supply for my 5m led strips (@5V, 14A max).
But my question is if it's also possible to power the arduino from the same powersupply, im not sure how to wire this :(.

Yes, it is possible.
Connect Power Supply to +5 Volts of Arduino.
Review the schematics.
Verify polarity twice because you will only get one chance if wrong.
