Power supply
A power supply includes a bottom case, a top cover, a circuit board and a heat-dissipating fan. In this case, the bottom case and the top cover are fitted together to delimit an accommodating space. The circuit board is mounted on the bottom case and located within the accommodating space. The circuit board is provided thereon with a plurality of electronic components and a plurality of heat-dissipating elements, each heat-dissipating element being provided correspondingly to one of the electronic components and allowed to conduct heat, respectively. Each of the heat-dissipating elements is provided with a mounting hole. The heat-dissipating fan includes a supporting frame, a driving module provided on the supporting frame, and a fan blade set covering the driving module and being driven by the driving module to rotate. Moreover, the heat-dissipating fan is not provided with a barrier wall around the fan blade set.
1. A power supply, comprising:
a bottom case and a top cover, said bottom case and said top cover being fitted together to delimit an accommodating space;
