Hello,

I have had good luck with cnc4pc products and I like the fact that many of thier parts plug into sockets so if something goes wrong you can just plug another in.

You will need to consider the voltage that your drivers can take, what the motors can use and the amps.
You can also build your own with the proper transformer, rectifier and caps.
Higher voltage helps with acceleration.

I'm running two 6amp stepper motor and one 3 amp stepper for z axis and the gecko drive are 80volts Max so I'm guessing a 45-70vdc 15amp power supply will be good? ?

It's really better to calculate the voltage needed than guess at it.

I have had good luck with Antek Power supplies.
