The current of the power supply unit is not so much the relevant value when used for steppers. The power is the important value. And the power is sufficient, as it should be at least 60W for the two steppers. The steppers require 7.2W per coil or 28.8W for both steppers. The power supply can deliver more than twice as much, which should be sufficient for the losses and the safety margin.
120W is definitely oversized. Or @christhebiss can get the 24V/3A version of his last link. 72W is more than enough, and a selectable voltage is not needed.
No matter how you slice it 2A is still 2A.
As coil current - yes. But that's not the current from the PSU. The stepper dirvers operate very similar to a buck converter. The higher the voltage of the PSU, the lower the current from the PSU. The PSU needs NOT to deliver the coil current - it needs to deliver the needed power.

I always tell new people to follow the manufacturer's recommendationd and not try to do something tricky that may or may not work.
Btw: how do i connect the suggested power supply to two drivers? Is there an adapter?
Will the motor wires need to be made longer in order to reach the drivers?
How far away will the power supply be from the two drivers?
It depends ok the exhibition place…but i thought there is one cable of the power supply and there two drivers each stepper…right?
So how im going to connect these?
Wire nuts for connection wires:
OR these WAGO connectors:
You will need also some wire
Wire AWG 16 (1.5mm²) long enough to connect everything.
Does it have exactly this size?
Can be anything less than AWG 16 such as 10, 12 or 14 but they are more expensive.
I found this in my workshop, would you think this is sufficient?
I did not see a better information on the cable. What you think?
The "12x0.50" looks like 12 separate conductors of 0.50mm^2. Maybe using 3 conductors in parallel would be the 1.5mm^2 equivalent of:
I got now everything you told me to organise.
Could please tell me how to split the power of the power supply that i can deliver both drivers?
Thanks!
It works perfectly, now I can try some various codes, thank you very much for your help, I really appreciated that, now I could push my project one step futher.
Best,
Chris
Glad you got it working.
Have a nice day!
