The recommended fuse levels for PSUs tend to be above the expected draw. Probably a safety margin for inrush or tolerable faults. Adding up the recommended fuse level on each PSU will probably be overkill. The start up of my 24V PSUs is naturally staggered as one will only power up after M80, which closes a relay that cuts the mains supply to the stepper/heater PSU.

The recommended fuse level is generally determined to protect the wire and not the device. Your fuses and breakers should trip before your wire would overheat and catch fire. In most industrial applications, the fuses and breakers are sized against the wire size and not the device loads as its much easier to replace the device than it is to replace all of the wiring.
