The following links will provide all the info to link multiple computer power supplies to get more power for your steppers.
I followed the instructions and now I am running 24 volts (actually 22.70 volts) to my steppers on my JCKleinbauer Hawk drill mill. The small steppers that seemed to be weak and stalling at 508mmm/min (20"/min) are now running well at 950-1000mm/min (~40"/min). :banana:
