stepper motor power needs

Question

i need stepper motors and have been wondering if it would be better to use a 5kg/cm or a 4Kg/cm motor.

They are rated 2.5A and 1.7A respectively. I wanted to use just a regular meanwell psu. is it better to go with the higher torque one and why?

i need the highest torque but am limited in power.

nema 17 models mentioned:

2.5A: SL42S247A

1.7A: 42BYGHW609L20P1X2

You could always dial the high torque/high current device back when high torque is not needed and save power that way. It would provide high torque when needed but low power when high torque is not needed. It might complicate your power supply though. If you don't need high holding torque, you might turn motor power right off when they aren't moving.
