Hi @vivekraj2992,

In general, you can use the USB power supply for most projects including the Advanced I/O demo that is available on the Nexys 4 DDR Resource Center which uses the all of the switches, LEDs, buttons, seven segment displays, VGA, DDR2 memory, built-in accelerator and more, so unless you were planning on running a much more extensive project, you can probably get away with never needing to use an external power supply. 

If you do want to use an external power supply, it will need to be a 5V power supply with at least 1A capability, as described in the Nexys 4 DDR reference manual here. Digilent has a 5V, 2.5A power supply that will work with Nexys 4 DDR available here.

Let me know if you have any questions about this.

Thanks,
JColvin
