A removable power supply system is proposed, which includes a power supply and a power supply adapter. The power supply adapter is fastened and electrically connected to the power supply. The power supply is provided with a first electrical connection portion and a first fastening portion. The power supply adapter is provided with a second electrical connection portion electrically connected to the first electrical connection portion and a second fastening portion fastened to the first fastening portion. In so doing, not only are the power supply and the power supply adapter fastened together, but individual power supply adapters are independent of each other, thereby solving the drawbacks of the prior art.

Removable power supply system

An apparatus for programmably converting the operating voltage of a CPU & chipset by means of the firmware programmably setting the operating voltage, instead of by means of adjusting jumpers, is disclosed. The apparatus includes an address decoder unit, a programmable data memory, a DC to DC converter and a feedback resistance switching circuit. In operation, the computer inputs an address signal and a data signal required for changing the operating voltage to the address decoder unit. After being decoded, the data is written into the programmable data memory. Then the programmable data memory outputs a selection signal to change the internal resistance of the feedback resistance switching circuit, thereby to convert the output voltage of the DC to DC converter.

An apparatus and method for switching the operating frequency of a computer host board by setting on a screen of the computer is disclosed. The apparatus and method use a frequency selection controller, instead of a switch or jumper selector used in a conventional apparatus and method, to control a frequency doubling factor required for the CPU and system chip set and a frequency selection signal output to a frequency generator. The switching operating frequency method is accomplished by manually activating the system to enable the system firmware to set a frequency doubling factor and an operating frequency when the system is powered up, outputting an address signal including the frequency and a frequency to be switched by a data/address bus after the system firmware sets the frequency doubling factor and the operating frequency, and decoding the address signal and locking the frequency data, whereby to change the frequency doubling factor output to the CPU and chip set and a frequency selection signal output to a frequency generator.
