## Long description

The FSP FSP720-20RAB is a 720 W power supply unit intended for use in standard ATX or PS/2 chassis for PCs and small servers. It provides redundant operation in Twins PRO configurations with hot‑swappable modules, enabling continuous power delivery when paired units are used. The unit is non‑modular, finished in black, and includes standard cables for CPU, PCIe, Peripheral (Molex) and SATA connections.
Advantages
The supply delivers up to 720 W total power with 80 PLUS Gold efficiency (approximately 90% typical), reducing energy losses and heat. Its 20+4 pin ATX connector ensures compatibility with a wide range of motherboards, while a 40 mm active cooling fan maintains stable operating temperatures. The Twins PRO redundant, hot‑swappable design allows instant failover between modules in redundant deployments, minimising downtime without requiring a front end bracket.

How to use
Install the PSU into a compatible ATX or PS/2 chassis according to the chassis manufacturer’s instructions, connect the 20+4 pin ATX cable to the motherboard and attach CPU, PCIe, Peripheral (Molex) and SATA cables to the respective components. For redundant Twins PRO setups, mount two compatible units in the chassis and follow the redundant module installation procedure to enable hot‑swappable failover.
