Addressable RGB LED Strip I am looking to create an addressable RGB LED strip circuit with my NodeMCU v3 Wi-Fi. I am looking at a strip of 150 RGB LEDs, 5 meters long, so 30 LED/m. But I am only going to use about 50 LEDs for the backlight on my desk. My understanding is that if each RGB LED pulls 60&nbsp;mA on full white, and I'm running 50 LEDs, then I will need at least 60&nbsp;mA x 50 LEDs = 3000&nbsp;ms (3&nbsp;A) of power to sufficiently light all of them. I am thinking about upgrading this in the future, and so I am thinking about going with a 5V 10A power supply. Am I okay to go with a 5&nbsp;V 10&nbsp;A power supply? Or will this be too much current for the system.
Each will only draw as much current as they normally would from a 5 volt supply. If you had a 5 volt 100 amp supply they still would not draw any more. 

The amount of excess current a power supply can deliver doesn't change what the load will take from that supply. 

For example, if you had a 5 volt supply with a 1 ohm resistor as a load the current would be 5 amps. 5 volts / 1 ohm = 5 amps. And if you had a 5 volt 10 amp supply the current would still be 5 amps. Same with a 20 amp supply. As long as the voltage is the same, going up in current capacity is safe.

(LEDs are not resistors but with this application it is much the same)

When you do wire up the LED strips make sure you are using thick enough wires.
