Power supply guide

Power supplies for the PCand the smartphone

The group of power supplies includes various designs that are available for the mobileor are suitable for installation in the PC. The general definition refers to a device which ensures the power supply for the respective electrical appliance. If currents and voltages deviating from the power supply are needed, that will do power adapter A compensation. Output current and output voltage can be freely selected or fixed.

Power adapters for Smartphoneand Co.

A plug-in power supply consists of a plug and a power adapter , The device allows the charging of electrical appliances via the AC mains in households. On the output side of many modern versions 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 the selection of a power supply, which is explicitly indicated for the respective model of the manufacturer. If the current, the voltage and the power match, then another model can be used. Would you not be suitable power adapter connect, charging will be lost or the smartphone will be damaged.

Built-in power supplies for larger power

If more or more voltages are required, the manufacturer usually provides built-in power supplies. They are installed in computers or video recorders. The services are usually several hundreds of watts. While touch protection is an essential safety feature for plug-in variants and must be ensured by law, the requirements for built-in power supplies are lower. Built into the computer, however, increases the overall security, as a shield is done to the outside. The „Corsair CP-9020097-EU ATX Power Supply“ is a safe and at the same time powerful model. It is characterized by its quiet operation. The noise is a key purchase criterion for built-in power supplies, since the power supplies are active during use of the computer. A high volume would be disturbing. The second important point is the performance, it is 550 watts in this model. Unlike power supplies for the smartphone, the voltage is not reduced but increased. If you need an even higher voltage, the „Be quiet! Pure Power CM BQT L8-CM-630W“ is the right choice. It can be up to 630 watts developed in an insignificant noise. The manufacturer emphasizes the efficiency certificate, which leads to savings and high performance.

The function of the power supply in the PC

PCs are already with the purchase with one power adapter fitted. Most buyers, however, do not pay attention to the data of the power supply when choosing the computer. If a simple model is installed, it can quickly suffer a defect. In this case, the replacement is necessary to continue using the PC. The power adapter must provide the power needed for the particular applications. A high-quality power supply works efficiently. When converting the voltages, as little energy as possible should be lost. However, if the appliance heats up during operation, this heating indicates a high energy loss. The heat is not only expensive but can 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 to work efficiently. The efficiency indicates what the ratio between used and recovered energy is. 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 will go unused. Select the power supplies so that they do not provide more power than can be obtained from the computer. If the PC is used as an office computer and used only for simple writing, 250 watts are usually sufficient. If 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 be 500 and more watts.
