Computer, Notebooks & Tablets: Power supply Video Guide

The group of power supply units includes various versions suitable for mobile phones or for installation in a PC. The general definition refers to a device that guarantees the power supply for the respective electrical device. If current intensities and voltages deviating from those of the mains supply are required, the power supply unit creates a balance. Output current and output voltage can be freely selectable or fixed

A plug-in power supply unit consists of a plug and a power supply unit. The device enables the charging of electrical appliances in households via the alternating current network. On the output side of many modern models there is a USB plug which is plugged into the smartphone. When selecting the respective products, you must pay particular attention to the technical requirements. The safest option is to select a power supply that is explicitly designated for the manufacturer’s model. If the current, voltage and power are the same, another model can be used. If you connect an unsuitable power adapter, the charging process will be switched off or the smartphone will be damaged.

If several or larger voltages are required, the manufacturer usually provides built-in power supplies. They are built into computers or video recorders. The power is usually several hundred watts. While contact protection is an essential safety feature of plug-in versions and must be ensured by law, the requirements for built-in power supplies are lower. Built into the computer, however, the overall security is increased, as the shielding to the outside is provided. The “Corsair CP-9020097-EU ATX Power Supply” is a model that is both safe and powerful. It is characterised by its quiet operation. The noise level is a decisive purchase criterion for built-in power supplies, as the power supplies are active while the computer is in use. A high volume would be disturbing. The second important point is the power, it is 550 watts on this model. In contrast to power supplies for smartphones, the voltage is not reduced but increased. The “Be quiet! Pure Power CM BQT L8-CM-630W” is the right choice for those who need an even higher voltage. Up to 630 watts are developed with only an insignificant background noise. The manufacturer emphasizes the efficiency certificate, which leads to savings and high performance.

PCs are already equipped with a power supply at the time of purchase. Most buyers, however, do not pay attention to the data of the power supply when choosing a computer. If a simple model is installed, it can quickly suffer a defect. In this case, the exchange is necessary in order to continue using the PC. The power supply unit must provide the energy required for the respective applications. A high-quality power supply works efficiently. As little energy as possible should be lost during the conversion of the voltages. However, if the device heats up during operation, this heating indicates a high loss of energy. The heat is not only expensive but can also cause damage. In the worst case, other components of the computer will be damaged. For this reason, the selection of high-quality products is important. They should be optimally dimensioned in order to work efficiently. The efficiency indicates the ratio between the energy used and the energy obtained. An efficiency of 90 percent is considered good, while an efficiency of 50 percent is too low. An efficiency of 50 percent means that the remaining 50 percent remain unused. Select the power supplies so that they do not provide more power than can be retrieved from the computer. If the PC is used as an office computer and only for simple writing activities, 250 watts are usually sufficient. If, on the other hand, you want to use sophisticated computer games, you should consider 400 watts and more. If several graphics cards are installed, the required power is even higher and can amount to 500 and more watts.
