Redundant 700 W ATX power supply

The FSP Twins Pro is a dual-module ATX PS2 unit that delivers up to 700 W through two hot-swappable modules. Under normal operation the modules share the load evenly, and if one fails the other continues powering the system without interruption. It includes FSP Guardian monitoring software and carries 80 PLUS Gold certification.

Suited for servers and always-on systems

This unit targets mail, web and home servers that require continuous uptime and the ability to replace a module without shutting down. Builders who need a single non-redundant supply or who lack space for a PS2 form factor should consider other options.

700 W shared across two modules

The combined 700 W output comfortably handles typical server workloads with multiple drives and expansion cards. Headroom diminishes when both modules are heavily loaded or when one module is removed, leaving the remaining unit to carry the full system demand.

Questions about this item

What motherboard connector must my board provide for the 20+4 pin main cable?

Your motherboard needs a standard 24-pin ATX socket; the supply's 20+4 pin plug fits either 20-pin or 24-pin headers.

Can I run the unit with only one module installed while keeping the other bay empty?

Yes, each module is hot-swappable so the system stays powered while you remove or replace the other unit.

How do I confirm both modules are sharing the load after installation?

Use the included FSP Guardian software to monitor real-time load split and LED status indicators on each module.
