Harry,
Using a bench supply for just the Crio should be OK. When you couple a bench supply to the PD and then try to feed some motors, there will be problems with drooping PD supply and thus the Crio reboots. Although you may find a high current power supply that is good to 35 amps peak like my Ham station power supply, it cannot handle the short circuit current of most motors in the KOP. The bench supply will go into current foldback or complete shutdown when trying to start one of these motors.
