## Summary description

The FSP FSP720-20RAB is a reliable 720 W power supply unit designed for PCs and servers. It features a 20+4 pin ATX connector, non-modular cabling, and 80 PLUS Gold certification for high efficiency. With an input voltage range of 100-240 V and a frequency of 50/60 Hz, it ensures stable performance. The active cooling system with a 4 cm fan keeps the unit cool during operation. Included cables: CPU, PCIe, Peripheral (Molex), and SATA.

## Long description

The FSP FSP720-20RAB is a high-performance 720 W power supply unit from the Twins PRO series, specifically engineered to provide reliable and redundant power for PCs and servers. Designed to fit standard ATX or PS2 chassis without the need for additional front-end brackets, this unit is an excellent choice for home servers, web servers, or mail servers. Its unique hot-swappable module design ensures continuous operation, as the secondary module immediately assumes the load if the primary one fails, effectively preventing unexpected system shutdowns.
Advantages
This power supply unit stands out due to its redundant architecture, which significantly enhances system uptime and reliability. The 80 PLUS Gold certification guarantees high energy efficiency of up to 90%, reducing power waste and heat generation. The inclusion of non-modular cabling simplifies the installation process, while the active cooling system, featuring a 40 mm fan, maintains optimal thermal conditions during intensive operation. Its compatibility with standard chassis types makes it a versatile solution for various professional and personal computing environments.
Suitable for
Home servers
Web servers
Mail servers
High-reliability workstation PCs
This unit may not be suitable for compact small form factor (SFF) cases that do not support standard ATX or PS2 power supply dimensions. Additionally, because it is designed for server-grade redundancy, it may be overkill for basic office workstations or standard home desktop computers that do not require high-availability power features.
Key specifications
Total power: 720 W
Efficiency: 90% (80 PLUS Gold certified)
Connector type: 20+4 pin ATX
Cooling: 40 mm fan
Compatibility: Standard ATX and PS2 chassis
Design: Redundant, hot-swappable modules
To use the FSP FSP720-20RAB, install the unit into a compatible ATX or PS2 chassis. Connect the 20+4 pin ATX cable to your motherboard and attach the necessary CPU, PCIe, SATA, and peripheral cables to your components. Ensure the unit is connected to a stable power source within the 100-240 V range. The hot-swappable modules allow for maintenance without powering down the entire system, provided the chassis allows access to the rear of the unit.
What to consider before purchase
Verify that your computer case supports standard ATX or PS2 power supply dimensions.
Ensure your motherboard utilizes a 20+4 pin ATX power connection.
Confirm that your system power requirements do not exceed the 720 W capacity.
For optimal performance and longevity, ensure the area around the 40 mm cooling fan remains unobstructed to allow for proper airflow and heat dissipation.
