Every PC, workstation, or server needs a proper PSU to work. When building a new PC, make sure to take your time when choosing this particular component as well. Aside from powering the PC, it can make your PC components last longer and save you some power. The 550W SilentiumPC Elementum E4 550W 80Plus EU ensures protected conduction of power from the mains to singular circuits, which then power the connected parts. The ATX source with a 550 W performance is an ideal solution for mid-range gaming and professional computers. The SilentiumPC source features a 120mm fan, which reduces the temperature and improves its service life. You can cut the electricity using a power switch. Every PSU has a special label that tells you its efficiency. The 80 PLUS tag indicates its efficiency reaches 88 %.
