The invention discloses a box type electric power steering controller which comprises a PCB, a base and a cover plate. Conical supporting columns and a heat conduction seat are integrally formed above the base. The PCB is arranged on the conical supporting columns and located through two locating columns penetrating the PCB, and the PCB is fixed to the heat conduction seat by being combined with screws. The cross sections of the two locating columns are different. The base and the cover plate are arranged together in a pressed manner. Mounting protrusions are inserted in corresponding mounting notches, and the conical supporting columns are located in the cover plate, so that the cover plate and the base are buckled more and more tightly. A triangular misloading prevention mark is arranged at the position, close to the right rear corner, of the top of the cover plate. Four rectangularly-distributed round columns extending upwards are integrally formed on the base, and thread mounting blind holes with the number equal to that of the round columns and positions corresponding to those of the round columns are arranged on the back face of the base. According to the structure, the problems that the base and the cover plate slightly shake after being mounted, the PCB and the base slightly shake after being mounted, the local temperature of the PCB is too high, and the PCB and the cover plate are placed reversely are effectively solved, and the dust prevention effect is achieved.
