A water-cooling radiator structure with pump includes a pump having a water outlet and a water inlet; and a water-cooling radiator including a first chamber that has a water-receiving room and a plurality of mutually communicable water passages therein. The water-receiving room is filled with a working fluid that reaches a level. The first chamber is externally provided with an outlet and an inlet as well as a pump mounting recess for mounting the pump therein. The water outlet and the water inlet are located corresponding to the outlet and the inlet, respectively, to be communicable with the water-receiving room and located lower than or flush with the level of the working fluid in the water-receiving room. And, the pump is detachably integrated into the water-cooling radiator. With these arrangements, it is able to overcome the problem of failed operation of the pump when the water-cooling radiator is laid horizontally.
