Fonte de alimentação FSP Twins PRO 500W 520 W 20+4 Pin ATX ATX preto

The FSP Twins PRO 500W is a redundant ATX PS2-sized power supply designed for stable operation in PC and server environments. Delivering a combined output of 520 W with wide AC input (100–240 V, 50/60 Hz) and 80 PLUS Gold efficiency, this unit is built for continuous loads and monitoring. It includes a 20+4 pin ATX motherboard connector, active cooling with a 40 mm fan, and fixed (non-modular) cabling including CPU, PCIe, Peripheral (Molex), and SATA connectors.

Advantages

The Twins PRO uses a dual hot-swappable PSU module design that balances power load between two modules and allows replacement of a failed unit without system downtime. A black round ribbon cable design improves heat dissipation and tidiness inside the chassis. The series also includes a power cord locking device to prevent accidental disconnects and supports connection to the FSP Guardian software via USB header for real-time monitoring of input/output power, efficiency, temperatures and system alerts.

Suitable for

• Home cloud servers
• Mail servers
• Small to medium-sized enterprise (SME) web servers
• PC systems requiring redundant power

How to use

Install the FSP Twins PRO 500W into an ATX PS2-compatible chassis and connect the 20+4 pin ATX connector to the motherboard along with CPU, PCIe and peripheral cables as required. Connect the unit to AC mains (100–240 V) and secure the power cord using the built-in locking device to prevent accidental disconnection. For redundant operation, install both hot-swappable PSU modules; if one module fails, swap it out while the other module continues supplying power.

Recommendations

Connect the Twins PRO to the FSP Guardian software via the internal USB header to monitor power, efficiency and temperature in real time, and schedule replacement of hot-swappable modules proactively based on usage and alert thresholds.
