48v power supply current for 4x 1HCL

[CNCModeller]

Hi All,
If I were to run 4 x 1HCL boards set to max (6.5A?) current per phase with NEMA 23 steppers in closed loop what power supply current rating would the team recommend assuming I'm driving a desktop mill so heavier use on X/Y and lighter us on Z/A where A is a rotary axis?

Everything else would be driven by separate 24v PSU(s) via a D3 Mini.

Any constructive thoughts would be much appreciated.

All the best
Barry M
