An improved power source device for monitors and host computers includes a first power source arrangement having a plug at one end and a capacitor parallel-connected at the other end which is electrically coupled with an internal circuit of a monitor for supplying a DC power to the monitor; and a second power source arrangement with a connecting component having input terminals electrically coupled with an internal switching power supply circuit of a host computer for obtaining a DC power therefrom, and output terminals connected to a socket fixed in a housing unit wall of the host computer; thereby, with the first and second power source arrangements connected together, DC power source will be directly supplied to the monitor from the host computer so as to eliminate any low-frequency and high-frequency interferences on the screen of the monitor. Additionally, with this simplified power source device, both the manufacturing cost and weight of the monitors are substantially reduced.
