I got some closed loop nema 23 steppers (3x 3N and 1x2.2N), with drivers and I'm not 100% sure wich PSU choose.

This ones:


Drivers are rated Vdc 24V-80V. The seller told me they use 24/36V 360W for two motors but reading the forum seems like using the higher voltage is better.

Any recomendations? Thanks!
