võimsustarvikut

A võimsustarvik, often translated as power supply unit (PSU) in English, is a crucial electronic component responsible for converting electrical power from a source, such as a wall outlet, into the correct voltage and current required by the various components of an electronic device. In computing, this is typically the power supply unit found within a computer case. It takes alternating current (AC) from the mains and transforms it into direct current (DC) voltages needed by the motherboard, graphics card, hard drives, and other internal hardware. The efficiency and reliability of a võimsustarvik are paramount, as a poorly performing unit can lead to system instability, data loss, or even permanent damage to connected components. Key specifications for a võimsustarvik include its wattage, which indicates the maximum power it can deliver, and its efficiency rating (e.g., 80 Plus Bronze, Silver, Gold), which measures how much energy is lost as heat during the conversion process. Modular võimsustarvikud allow for the disconnection of unused cables, improving airflow and cable management within a device.
