Question Power Supply got Tripped when using as 12V Power Source.

[yusha1962]

I want to use my computer power supply as 12V 18A power source without got damage and tripped.

motor specs: 12V 18A. (picture mentioned)

power supply has specs mention it support max 18A on 12V. (picture mentioned)

when I turn on the motor after seconds power supply got trip, after 2 minutes later agin same happens.

thanks in advance.

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.

Brand and model of the PSU?

Old group regulated unit. You can't use it for 12v only. You also need the draw power from the 5v line.

Triple 12v rail with 18A each and 39,6A combined. With which connectors is de PSU connected to the motor?

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

I would stop trying to rig something up and buy a converter.

Power source for what?

What 'motor' is involved here?
