Do I need power supply totalling my ampcurrent needs to maxmaximum of my ampcurrent needs?

My prototype project has these 3 components currently:

  • US-17HS4401 Stepper Motorstepper motor, Ratedrated at 12V / 1.7A
  • MIG-400 6V DC Motormotor, 6V / 10A max (thoalthough it was spinning fast enough at 3.75A)
  • Particle Photon, 5V / 0.5 A
  • 2x L298N Driver Controllerdriver controller (reduces voltage to motors by 2V)
  • 1x DC-DC LM Voltagevoltage regulator.

I'm looking to buy a power supply for my project. Looking at this the total current draw is: 5.95A, the maxmaximum draw is: 3.75A

  1. My question is does the power supply need to add up the ampscurrent required or just provide the maxmaximum required  ?
  2. Since each device has different current requirement do I need to add a step down module for amps before each device  ?

What will happen if my device is given more amps than provided  ? Do I need to place before it any safeguards  ?
