Will this power supply be sufficient?

Im confused on how the whole current from power supply to stepper driver is handled.

Im looking at the 48v 7.3a power supply with 3 of the KL-5042 drives. The motors Im powering are from Probotix and are these:

I will be most likely running them in bi-polar series as most of my drive system is roller chain and sprocket, so High speed isnt needed. But I would like to be able to try to run in parallel if the need arises. Will this power supply be sufficient or will I need to go to the 48V 10A?

why not check cncrouterparts?

That doesn't really answer my question, And also I don't want to spend 300$ on a gecko drive when I can get the Keling drives for 120$ right now. So Back to the question, will that amperage be sufficient or do I need to go for the higher amperage PSU?

The 7.3a supply will be fine.
I run (3) kl6050's parallel with (3) 5a 570 steppers with that supply no problem.

Why thank you Hoss, that was exactly what I was hoping for.
