30 magnets (doors NC) is connected to an I/O device in a cabinet. Will a 10A power supply to the cabinet be enough, when each is drawing 95mA. Or should one get a bigger power supply to be safe?

Welcome to the forum mate.
I'm presuming each door will be wired back to an output in the I/O module. What does the manual say for the power to the I/O module?
What else is going in the cabinet.
