It seems that you're still stuck on the idea that the voltage has to be 1.5v. Voltage will be
different for every different size part you try to plate. Ignore the voltage. Make your adjustments to get the appropriate current, and voltage will be whatever it needs to be.
In the case of the hose clamp, 4-5" should be plated at .3-.5 amps (old formula still?). At this amperage you'll only see about .5v.

but this bussiness of the PS kicking off has me scratching my head, I mean after all it is a 30V-30A power supply!

The
size of a power supply has nothing to do with it's quality.
One of two things may be happening here:
1) Your power supplies are tripping because they think they're in short circuit. As you move part closer to the anode, the current increases, and they hit their "trip" point.
A well designed power supply will deliver it's current into a dead short. Lower cost supplies will have a circuit breaker to prevent supply burn out.
or ....
2) As the current increases, they reach the constant voltage/constant current switch over point.
Tell us more about the new power supply. Do you have a current control knob, or only a voltage control knob?
