5V 4A power supply for simple circuit

Question

I am a 14 year old electronics noob. I am mostly a programmer and mechanical designer. I have been working on a robot which needs around 4 amps of current. I am thinking about using a simple 5V 4A AC to DC adapter but they seem to be a pain to connect to a PCB. Especially since many mounts cannot even work with 4 Amps. I am trying to power 4 micro servos.
EDIT: How can I power this?
Edit 2: here is an image of my planned circuit:

Edit 3: There is a slight error in the circuit diagram in servo 2: pin 2 of that is supposed to be connected to pin 6 of the Arduino.

If there's a way to split up your servo supplies, you could get away with two 5V/2A supplies, like for example fast-charge USB wall warts. That might be more compact than a typical off-the-shelf open-frame supply.

there are plenty of options...
don't know what your best dealer or online shop is, but for a PCBs things like that work perfectly:

you get em in all sizes, for all currents. Just search / ask for some good shops in your area of the world.
Maybe you even want such gernan called "Federzugklemme" (spring-type terminal) where the contact is achived with a stong metal spring. they have perfect contact. skrewed terminal might get loose by vibration. spring-type terminal are the better choice in that case
