It's still highly recommended to put a 1000 uF capacitor on the +5V powerline, since the WS2812B are very sensitive LEDs.http://www.tweaking4all.nl/hardware/arduino/arduino-ws2812-led/I think i've burned about 10 of them while testing The good thing is that you only need to 'cut' of the first LED, since the rest is still good (if it happens)
