Replacement Module for Twins Pro 500W

This is a single replacement module designed for the FSP Twins Pro 500W ATX PS2 1+1 redundant power supply. It delivers up to 500 W through a single +12 V rail and meets 80 Plus Gold efficiency with greater than 90 % performance. The unit complies with ATX12V and EPS12V standards and the UL 62368 safety standard.

Who This Suits and Who Should Look Elsewhere

System administrators running servers or workstations that require continuous uptime can hot-swap a failed module without shutting down. Builders assembling a new system or upgrading a non-redundant chassis should look at a standard single-unit power supply instead.

ATX PS2 Redundant Form Factor

The module measures 190 mm in length and follows the ATX PS2 redundant size specification. It is non-modular and built to slot directly into the Twins Pro chassis for tool-free replacement.

商品問答

What comes with the FSP520-20RAB module and what else is needed for a redundant setup?

The package contains one hot-swappable module rated at 500 W with 80 PLUS Gold efficiency. A second identical module and the Twins PRO 500W chassis are required to form the 1+1 redundant power supply.

Which module variant matches the Twins PRO 500W chassis?

Choose the FSP520-20RAB module; it is the designated replacement for the Twins PRO 500W and delivers the full 500 W capacity with 80 PLUS Gold certification.

What does the 500 W rating mean once the module is installed in a server?

Each module can supply the full 500 W load on its own; during normal operation two modules share the load, and if one fails the other continues delivering up to 500 W without interruption.
