Redundant ATX Power Supply

The FSP TwinsPro500 is a 500 W ATX power supply built around two hot-swappable modules in a PS2 form factor. It targets mail, web and home server or office systems that must stay online when a single module fails. The 24-pin main connector and four 6+2-pin PCI-Express connectors feed standard components, while six SATA power connectors serve storage drives. Guardian monitoring software connects via a USB header for real-time status.

Gold Efficiency and Quiet Operation

The unit meets 80 PLUS Gold certification and exceeds 90 percent efficiency, reducing waste heat and fan noise during normal loads. Load sharing between the two modules keeps each one running cooler and quieter than a single 500 W supply would. Full protection covers over-current, over-voltage, short circuit and fan failure events. A power cord locking device prevents accidental disconnects, and the round black ribbon cables aid airflow inside the chassis.

Drop-In Redundancy for Standard Cases

At 190 mm long, the PS2-sized housing fits regular ATX layouts without a front-end bracket. Non-modular cables are fixed, so builders must route the full set of 24-pin, PCI-Express and SATA leads. Hot-swappable modules slide out from the rear while the system runs, eliminating downtime for replacements. LED status indicators on each module show health at a glance, and Guardian software logs input, output and efficiency data for remote oversight.

Domande su questo articolo

How do I install the FSP TwinsPro500 in a standard ATX case and what step is often missed?

Fit the 190 mm long ATX PS2 chassis into the case, connect the 24Pin main connector plus the four 6+2-Pin PCIe and six SATA leads, then plug the USB header into the motherboard so the FSP Guardian software can monitor the redundant modules.

What maintenance or replacement will the TwinsPro500 need over time?

Each hot-swappable module can be pulled out and replaced while the system stays running; the LED status indicator shows which unit has failed, and the power cord locking device should be checked periodically to ensure it still holds the AC cable securely.

What limit appears first when the TwinsPro500 runs under sustained load?

The 500 W maximum power rating is the first ceiling; the single +12V rail and 80 PLUS Gold efficiency above 90 % keep thermals in check, but continuous draw beyond 500 W will trigger over-current protection.
