WS2812B RGB LED STRIP 60/M 5VDC spec:
Each WS2812 LED with all three colors at full brightness will use 60mA. A meter length will thus be 60 x 60 = 3600mA or 3.6A. Now keep in might that that will be the absolute max with all 3 colors at full brightness, normally colors are made up with 1-3 LEDs on at different brightness and depending on the patterns you create all LEDs are not always all on at the same time. You can thus go lower but to ensure your power supply will not overwork itself 5V@3.5A will work well. A 5m meter rail will work great with a 20A 5V power supply.
