FSP900-50REB: 900W PS2 Redundant Power Supply for ATX-to-Redundant Upgrades
The FSP900-50REB enables compatible ATX-based systems to upgrade from a conventional single power supply to a 900W PS2 redundant power architecture. Standard ATX screw holes, multiple bracket options, and a 1G-sized mechanical design support installation in commercial ATX chassis, PS2 enclosures, industrial computers, and rack-mount server chassis 3U and above.
Replaceable hot-swap modules help reduce service interruptions and support cost-effective power upgrades within the 400W to 900W series. ATX 12V and EPS 12V compliance, 80 PLUS Gold efficiency, and low ripple and noise further support stable operation in server, workstation, and industrial computing systems.

Standard ATX Screw Holes and Multiple Brackets for Easy Installation
Standard ATX screw holes allow the FSP900-50REB to replace a conventional ATX power supply without requiring an additional front-end bracket. This familiar mounting method helps reduce chassis modification and installation effort when adding redundant power to compatible ATX-based systems.
Four bracket configurations provide additional flexibility for different chassis mounting layouts. System builders can select the appropriate fixing method for tower servers, industrial computers, and rack-mount server chassis 3U and above. The installation remains close to a standard ATX PSU layout, helping reduce mechanical changes.
Hot-Swap Redundant PSU with Replaceable Modules and Automatic Failover
Hot-swap capability helps reduce maintenance downtime by allowing a failed power module to be replaced without shutting down the complete server or industrial computer. During normal operation, the two modules use separate power channels to share the system load and maintain stable output. If either module fails, the remaining module automatically takes over power delivery within the supported system load.
Replaceable modules also provide a cost-effective path from lower to higher power output. Instead of replacing the complete power supply assembly or changing the chassis design, system builders can replace the installed modules with compatible higher-output modules from the 400W to 900W series.
A smart power status LED supports faster fault identification. PMBus or USB communication firmware supports power supply communication with the host system. These functions help simplify troubleshooting, module replacement, and ongoing system maintenance.
Applications for the FSP900-50REB 900W Redundant Power Supply
The FSP900-50REB supports server, workstation, and industrial computing applications that require 900W output, redundant operation, and serviceable power modules in an ATX- or PS2-based chassis. Suitable applications include:
- AI computing systems requiring higher power capacity and improved power availability
- Visual computing systems supporting graphics-intensive processing and extended operating periods
- Edge computing platforms deployed in tower systems, industrial computers, or rack-mount server chassis 3U and above
- Graphic workstations where an unexpected power module failure could interrupt professional workloads
- Multi-function servers requiring automatic failover and hot-swap maintenance
- Industrial computers and IPC controllers designed for long operating hours and easier field servicing
- Automation controllers requiring stable power delivery and reduced maintenance interruptions
