You need to provide a whole lot more information in order to even guess at the answer!
Are you:
Drawing, knife cutting, 3d printing, cutting wood, cutting aluminum, cutting steel?
Ball screw, belt drive, acme screw, acme with anti-backlash?
Air bearing, ball slides, wheels, plastic bearings, metal on metal?
Plastic frame, aluminum frame, steel frame, cast iron frame?
Slow, faster, very fast, extremely fast?
Wood accuracy, metal accuracy, extreme accuracy?
On a tight budget, have money, price is no object?

I ordered the questions by increasing cost or difficulty from left to right.

Okay,
My machine is half the size of yours, has 20mm x 5mm pitch ball screws driven by 800 in/oz. steppers at 68 vdc.  The steppers are also low impedence.  No problem with power and it is very quick, up to 3000mm/min. I can cut steel with no problem. I don't think this helps you much.

My power supply is a 120 vac x 24/48 vac transformer rated at 750 va. It feeds a full wave bridge rectifier and a large capacitor (don't recall the size) at 48 volt ac so that the unregulated DC voltage is about 68 volts. My drives are rated for 80 vdc input. If all the axis were slowing down at the same time putting power back into the supply the voltage might rise well above the drives maximum rating, so I have a large zener diode across the output to keep that from happening.
