No computer, workstation, or server can operate without a good PSU. When building a new PC, make sure to take your time when choosing this particular component as well. Aside from supplying power to the PC, it can also improve the component service life and save some money and power. The 550W GIGABYTE P550B ensures reliable conduction of electricity from the mains to individual circuits, which subsequently power all the components. The ATX PSU with a 550 W performance is an ideal solution for the more powerful mid-range PCs. The GIGABYTE source features a 120mm fan, which lowers the temperature and improves its lifespan. The noise is under 40 dB. You can cut the electricity using a power switch. Every PSU features a label that tells you how efficient it is when it comes to input power. The 80 PLUS Bronze marker indicates an efficiency of up to 85 %.
