This article is about what power means in a computer. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Power means power by default in the computer. Press the Powerbutton on the computer and you can turn off the computer. The power supply provides the electricity needed by all the parts in the computer. The power of the power supply and the stability of current and voltage will directly affect the working performance and service life of the computer.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Power means power by default in the computer. Press the Powerbutton on the computer and you can turn off the computer.

The power supply provides the electricity needed by all the parts in the computer. The power of the power supply and the stability of current and voltage will directly affect the working performance and service life of the computer.

The computer power supply changes the alternating current through a switching power supply transformer into a stable direct current, such as 5V, 5V, 5V, 12V, 12V, etc., to supply the system version in the mainframe, floppy disk, hard disk drive and various adapter expansion cards and other system components. Generally speaking, one power supply is broken, and another backup power supply replaces it.

You can also enhance the availability of hardware by providing battery backup for nodes and disks. Uninterruptible power supplies (UPS) supported by HP, such as HP PowerTrust, can beware of instant power outages. The disk should be connected to the power supply circuit in such a way that the mirrored copies are connected to different power supplies. The root disk and its corresponding nodes should be powered by the same power circuit.

Extended data

DC power supply (DC power) has two positive and negative electrodes, the potential of the positive electrode is high and the potential of the negative electrode is low. When the two electrodes are connected with the circuit, a constant potential difference can be maintained between the two ends of the circuit, thus the current from the positive electrode to the negative electrode is formed in the external circuit.

Ac power supply can provide a stable voltage and frequency power supply called AC stable power supply. At present, the work done by most domestic manufacturers is AC voltage stability. Parameter adjustment (resonance) type of voltage regulator, the basic principle of voltage stabilization is LC series resonance, the early emergence of magnetic saturation regulator belongs to this category.

Its advantages are: simple structure, no many components, high reliability, wide voltage stabilization range, strong anti-interference and anti-overload ability. The disadvantages are: high energy consumption, high noise, bulky and high cost.
