Single Replacement Module

This is a single replacement module for the FSP Twins PRO 900W ATX PS2 1+1 redundant power supply. It delivers up to 900 W of power and fits the 190 mm ATX PS2 redundant form factor. The module carries 80 PLUS Gold certification for efficient operation. Hot-swappable design allows removal and installation without system shutdown.

Ideal for Redundant Server Builds

The module suits administrators who need a spare or replacement unit to maintain N+1 redundancy in an existing Twins Pro 900W chassis. It is not suited for standalone ATX builds that lack the redundant frame and backplane required for hot-swap operation. Builders without a compatible Twins Pro enclosure should look at conventional single-unit power supplies instead.

900 W Redundant Module Decides Fit

The defining specification is the 900 W redundant module rating paired with the 190 mm ATX PS2 form factor. Only systems designed for the Twins Pro 1+1 redundant architecture can accept this module. Confirm your chassis supports the Twins Pro backplane before purchasing.

Questions about this item

Does the module ship with cables or a chassis, or must I buy the Twins Pro housing separately?

This is a single hot-swappable module only; the redundant chassis and all cables are sold as part of the complete Twins Pro 900W unit.

The listing shows one module rated at 900 W — is that the capacity per module or for the pair?

The 900 W figure applies to the full 1+1 redundant assembly; each module is designed to operate inside that chassis.

What does the 80 PLUS Gold 230 V rating mean for everyday efficiency in a server?

At 230 V input the module meets Gold efficiency targets, reducing waste heat and power draw during continuous operation.
