550W power supply – the most important things at a glance

A 550W power supply is an ideal solution for mid-range gaming PCs or workstations that require stable and reliable power flow. Manufacturers such as Be Quiet!, Corsair or EVGA offer various 550W power supplies, which mainly differ in their efficiency class (80 PLUS Bronze, Silver, Gold or Platinum), fan size and the option of modular or non-modular cable routing. The efficiency class provides information about the energy efficiency of the power supply, while the fan size influences the noise level. With a modular cable routing, unnecessary cables can be removed, which leads to better air circulation in the case and thus to a lower system temperature. Depending on the equipment and manufacturer, 550W power supplies are priced between 50 and 100 euros. Before deciding on a specific model, however, you should check the power consumption of the built-in components and make sure that the 550W power supply is sufficient.
