Replacement Module for Twins Pro 700W

This single module replaces a failed unit inside the FSP Twins Pro 700W redundant power supply. It is designed for system builders and IT staff who need to restore redundancy without swapping the entire chassis. The module fits the ATX PS2 form factor used by the Twins Pro platform. Hot-swap capability lets you exchange it while the system stays online.

80 Plus Gold Efficiency and Thermal Behaviour

The module meets 80 Plus Gold certification with efficiency greater than 90 percent at typical loads. Under normal operation the twin modules share the load evenly, which reduces the current handled by each unit and keeps internal temperatures lower. Hot-swap design means a faulty module can be removed without shutting down the server or workstation. Compliance with UL 62368 confirms the safety envelope for continuous operation.

Hot-Swap Restores Full Redundancy

Swapping in a fresh module instantly returns the power supply to 1+1 redundant mode so the remaining unit no longer carries the full load alone. No additional cables or configuration tools are required because the module uses the existing Twins Pro backplane connectors. The changeover is transparent to the operating system and attached hardware. This keeps servers, workstations and critical home systems running without interruption.

Questions about this item

How do I install the FSP Twins Pro module into the 1+1 chassis and what step is often missed?

Slide the module into the ATX PS2 bay until the latch clicks, then secure the retention screw; the step often missed is tightening that screw, which keeps the hot-swap connector fully seated.

What maintenance or replacement will this 700 W module need later?

The unit is a field-replaceable module; if a fan bearing wears or efficiency drops below 80 Plus Gold, swap the module without tools — no internal capacitors are user-serviceable.

What limit appears first when the module runs at full 700 W load continuously?

Thermal protection engages first; the redundant design shares load between two modules, so sustained 700 W on a single module triggers over-temperature shutdown before any electrical limit is reached.
