Product information

Description

The FSP Twins PRO 900W 20+4 pin ATX PS/2 Black is a redundant power supply unit designed for standard ATX or PS/2 chassis and intended for server or continuous-operation environments. This non-modular unit provides a combined rated output of 900W, supports AC input from 100–240V, and is equipped with two 4 cm fans for cooling. The product includes a 20+4 pin ATX connector and comes in a black finish; it is engineered to operate as part of a Twins PRO redundant system with hot-swappable modules for uninterrupted power delivery.

Advantages

The Twins PRO design incorporates redundant, hot-swappable modules so one module can immediately take over if the other fails, minimising downtime for mail, web or home servers. An 80 PLUS Gold certification ensures higher efficiency under typical loads, while the round black ribbon cable design promotes cleaner cable management and improved heat emission. A power cord locking device secures the mains connection against accidental disconnection. The unit is compatible with an FSP Guardian monitoring setup to report input/output metrics and temperature warnings when connected to a system USB header.

Suitable for

  • Small home servers and NAS devices
  • Mail and web server deployments in compact ATX/PS2 chassis
  • Continuous-operation systems requiring redundant power
  • Custom builds needing compact, reliable PSU modules

Key specifications

  • Total rated output: 900W (redundant combined)
  • Connector: 20+4 pin ATX
  • Certification: 80 PLUS Gold
  • AC input voltage: 100–240V
  • Cooling: two 4 cm fans
  • Design: non-modular, redundant hot-swappable modules
  • Colour: Black
  • Power cord locking device included

How to use

Install the Twins PRO unit into a compatible ATX or PS/2 chassis following standard PSU mounting and grounding practices. Connect the 20+4 pin ATX connector to the motherboard and attach required peripheral power leads as applicable. For redundant operation, mount both hot-swappable modules and ensure the power cord is secured with the locking device. If available, connect the unit to a system USB header and install the FSP Guardian software to monitor power and thermal parameters in real time.

Usage recommendations

Place the PSU in a well-ventilated enclosure to allow the two 4 cm fans to provide effective cooling, and use the power cord locking device to prevent accidental disconnection. Regularly monitor status via FSP Guardian when connected to ensure temperature and load remain within recommended ranges.
