## Long description

FSP Twins PRO 500W is a redundant ATX PS2-size power supply unit designed for PC and server applications, delivering a combined total output of 520 W with an AC input range of 100–240 V at 50/60 Hz. This non-modular PSU is 80 PLUS Gold certified for high efficiency and uses an active cooling system with a 40 mm fan. The unit provides standard connectors including a 20+4 pin ATX motherboard connector, CPU, PCIe, Peripheral (Molex) and SATA cables. The Twins PRO series employs a dual hot-swappable PSU module concept that maintains continuous power delivery for home cloud, mail or small-to-medium web server systems.
Advantages
The Twin Pro modular design splits the power load between two hot-swappable PSU modules to improve efficiency and reduce noise; if one module fails the other continues supplying power until a replacement is inserted, allowing module replacement without system downtime. A black round ribbon cable design supports heat dissipation and cleaner cable management, extending component lifespan and improving internal airflow. The power cord locking device secures the mains cable against accidental disconnection to help maintain stable operation. When connected to a motherboard USB header, the PSU can communicate with FSP Guardian software for real-time monitoring of input/output power, efficiency and temperature, providing alerts when thresholds are exceeded.
Suitable for
Home cloud or NAS servers
Mail servers and light-duty server tasks
Small-to-medium enterprise (SME) web servers
PC systems that require high-efficiency redundant power

How to use

Connect the mains cable and secure it using the power cord locking device. If monitoring is desired, attach the unit to a motherboard USB header and install the FSP Guardian software to view real-time metrics and receive alerts. During maintenance, individual PSU modules can be hot-swapped while the other module maintains power to the system, avoiding shutdown.
Usage recommendations
Use the Twins PRO in systems where uninterrupted power is important; ensure the chassis supports ATX PS2 format and provides adequate airflow for the 40 mm fan. Keep FSP Guardian installed and configured if you need temperature and power input/output monitoring, and replace failed modules promptly using compatible FSP Twins PRO modules to maintain redundancy.
