You will overload the power supply and it will fail sooner or later.

@Tes yeux noirs,
Thanks, Tes, I kinda figured as much but I wasn't sure.

The current rating is given by the manufacturer and specifies the maximum amount of current that can be continually drawn without damage or affecting the performance. You need a 3.5 amp of 4 amp power supply. 5 amp would be better. Also it should be rated for motor use.
