FSP Group FSP220-50FGBBI 220W 80+ Bronze Power Supply

FSP Group FSP220-50FGBBI is a compact Flex ATX power supply with a power output of 220W, aimed at small systems, office machines, thin cases, and embedded solutions. The case is black and has very modest dimensions, giving you freedom for more atypical or space-constrained configurations. The certified efficiency of up to 85% means fewer losses and lower consumption from the outlet compared to cheap no-name variants. Add Active PFC, and you get a more stable and clean power supply for your components.

What you get – 220W is fully sufficient for systems with an economical CPU, without a separate high-end GPU, home servers, router/firewall cases, or POS terminals. The input power range of 100 – 240 VAC makes the unit suitable for various electrical grids and more stable during voltage fluctuations. The Flex ATX format is key if you work with low-profile or OEM cases, where a standard ATX power supply simply will not fit. The modular implementation allows you to keep only the necessary cables in the case, which facilitates cable management and improves airflow. The declared MTBF 100 000 hours at 25℃ speaks to a long expected lifespan at normal temperature and load.

• Power 220W – suitable for economical systems without a heavy GPU, NAS, office configurations, and small servers.
• Input power 100 – 240 VAC – works reliably both at lower and higher grid voltage, useful in an unstable electrical grid.
• Flex ATX format – compact dimensions 150 x 81.5 x 40.5 mm, ideal for small cases and custom solutions with limited space.
• Efficiency 85% – fewer losses as heat and a lower electricity bill compared to less efficient power supplies in the same class.
• Modular power supply unit – remove unnecessary cables, facilitate assembly, and improve airflow in compact cases.
• Active PFC – better power factor and more stable voltage delivery to components, especially under load.
• MTBF 100K hours at 25℃ – an indication of a long lifespan under normal conditions and quality internal components.
• Warranty 24 months – two years of peace of mind when used in a work or home environment.

This power supply is suitable if you are building a small, energy-efficient machine – an SFF office PC, home server, network device, or industrial/POS computer, where space is critical. It is not a good choice if you plan a powerful gaming build with a serious GPU or many additional devices that will exceed the reasonable limit of 220W.

The combination of Flex ATX format, 220W power, 85% efficiency, and modular design makes the FSP220-50FGBBI a very practical solution for compact and reliable systems, where every millimeter and every watt matters.
