I have a project where I'm looking to power 120 RGB LEDs in a strip (WS2812B).
Obviously an Arduino Micro cannot supply this amount of current so I'm looking to use an external 5V/4A switching power supply (wall-wart) to power the LED's as well as the Arduino.
My question is, can I just split the power from the wall-wart providing 5v_reg directly to the 5V pin on the Arduino Micro and 5v_reg to the LEDs Vss?
It it necessary to use extra bypass capacitors in this case?

Yes. As long as it is a clean regulated 5V supply.

No.
