DC motors have inrush current on starting which is generally 3x the running current. So if that is 18A of running current you either need a 54A PSU to start it or else some circuitry to limit starting current.

And also note the design of the PSU matters as well--some don't take kindly to having only a load on one voltage rail.

how did you wire that motor with your PSU?

two power and two ground wires should be minimum, if it still trips, use three power and three ground wires
