Choosing a power supply

[phantomcow2]

I am now ready to buy the last link of my cnc mill conversion - power supply.
I believe a 24v is the ideal thing for my setup. I am using a Hobby CNC 4 axis board with 3 stepper motors;
5.4VDC 1.5A

I think thats what is needed here. WHen i select a power supply is there some factor i need to look for or anything?
Would this one work?

I don't use the Hobby CNC board, but I do use that power supply. It works fine and I think that its a good value.

You will need to get a 110v cord. I used one off of an old printer and cut the female end off.

Voltage and current rating. Is that the voltage and current rating for each phase of each stepper? If so, then you'll be better off with a supply with a higher current rating....3steppers X 2 phases per stepper X 1.5 amps perphase = 9 amps. With PWM you can probably by with 4.5 amps....but you'll be at the limit....Not sure what the Hobby CNC max voltage is....but a 48 volt supply at 10 amps would be your best bet. Plus since you have a 4-axis card...you could support an additional stepper.

MPJA has a 28VDC 14A supply for under $40 bucks. Plenty of performance with this one!

Oh and with that one i posted a link for, I would imagine this one could also support another stepper right?
