Is in every

All devices receive energy from the power supply — it is in every computer, and converts the voltage of 220V to voltage from the network with indicators acceptable for devices of the system unit. It is with the check of the power supply that the diagnosis should be started if the computer does not turn on or works incorrectly. Low -quality power supplies fail quickly, especially if the PC is actively operated. And it’s good, if only the block itself breaks, often its breakdown entails and malfunctions of other elements. It is possible to protect the power supply itself, as well as all the devices inside the system unit using the UPS or a good network filter. Often the cause of the breakdown is a jump in voltage in the network or frequent shutdown of electricity, which is why you need to purchase additional equipment.
