Running 4 axis from a ps806 or sps705 psu

The PS806 is by far a better solution.

Not really Gary.!! . . . . To run 4 x 4.2A motors he'll need 2 x PS806 thats £204 plus del For less than 1 PS806 he can build a supply that will easily give what he needs and still have change to buy a small 5V 1A reg supply.!

Inrush is not a problem @ 600Va and easy enough to build an inrush circuit if really needed.! ( Which it won't be in most case's)

still have change to buy a small 5V 1A reg supply.!

Don't need much change for that :)

Yep but I find folks under stand better when it's spelled out and the difference known.? He could have been wondering why or how 24V could give him 65+V.?

I guess.

Was thinking something a bit easier and neater than that.!!

Edit: I've had 2A version of these for £5 before this was just an example.

What is said was the PS806 is a far better solution to the PS705, not just because of the size difference but also because its linear and linear power supplies are far better suited for stepper and servo applications.
The advantage is that the PS806 can handle quick changes in current draw a lot better than the PS705.
Looking at the spec, the PS806 is cutting it very close and ideally you would need about 8-10A of peak current, however I have run 3 X 6.2A motor from one of these with no problem at all and the voltage is still in 60V range.
Next week i will power one up with 4 AM882 and SY60 motors and monitor the current and voltage and report back to you.
