The Synology PSU 550W-RP MODULE_1 is a replacement power supply unit engineered for NAS and rack storage systems. Delivering up to 550 watts of continuous output in a compact module, this power supply is intended to maintain stable operation for compatible Synology server models such as FS3410, SA6400 and RS3621RPxs. Its compact housing and grey finish are designed for easy installation in constrained server bays and redundancy configurations.

Advantages

This power module provides a consistent 550W output to support storage-intensive workloads and drive arrays. Its compact form factor reduces space consumption in rack and chassis layouts while allowing hot-swap or redundant power arrangements where supported by the NAS. Built to match Synology hardware interfaces, the unit facilitates straightforward replacement and integration with minimal downtime.

Suitable for

• Rack-mounted NAS systems requiring a 550W power module
• Redundant power configurations in enterprise or small business storage
• Replacements for failed or degraded power modules in compatible Synology models
• Environments with limited space that need compact PSU modules

Key specifications

• Maximum power output: 550 W
• Form factor: compact module suitable for compatible Synology chassis
• Dimensions (approx.): 224 mm (width) × 74 mm (depth) × 39 mm (height)
• Color: grey
• Intended use: external/internal power module for NAS and rack storage servers

How to use

Before replacing a power module, power down the NAS or follow the manufacturer’s hot-swap procedure if the device supports hot-pluggable power modules. Remove the faulty module according to the server manual and insert the Synology PSU 550W-RP MODULE_1 until it seats securely in the module bay. Ensure connectors are fully engaged and any retention latches are fastened. After installation, power on the system and verify that the NAS recognizes the new module and that any status indicators show normal operation.

Recommendations

Install and service this power unit in a clean, dry environment within the operating temperature and humidity ranges specified by your NAS vendor. Use the power module only with compatible Synology models to ensure proper mechanical fit and electrical compatibility. For systems using redundant power, replace failed modules promptly to restore full redundancy. Dispose of the replaced unit according to local electronic waste regulations.
