So that is 1 supply per 2 drivers/motors.
With nema34's you get 1 supply per axis.

This 48v 600w supply here says it will drive 4 of there 8 wire motors when in parallel. I can't see why one of these wouldn't be fine for yours:

However if it seems a bit close to max they also do a 48v 480w version which you could opt for, buy 2 of them and put 1 supply per 2 motors. (Or go all out and just get 2 of the 600's. they'll prob run at half power and last for life!)

Their similar motors they suggest the supplies for are 4A and 3mh inductance in parallel and 12mh in series. Series would require more power.

I have these exact above motors working on 60v. (I have the 24-80v type drivers)

I'm considering having a crack at building a toroidal supply to output around 55vdc so I can ditch my meanwells and make some space in my control box.
I'll say it again so if the OP decides to ignore the advise and go with 48V he cannot say he wasn't warned.!!! . . . . . 48Vdc is too close to the drives Max rating and it's only a matter of time before it gets damaged.

Why anyone would fit a PSU on each drive is beyond me.??
