QNAP 300W Single Power Supply for 2U Rackmount NAS/NVR

The QNAP SP-8BAY2U-S-PSU is a 300-watt single power supply module built for 2U rackmount NAS and NVR systems. It serves as a direct replacement for the factory unit found in models such as the TS-809U-RP, TS-859U-RP, and VS-8024U-RP, restoring full power redundancy in minutes.

Engineers designed this module to slide into the existing power bay without tools or rewiring. Once seated, it automatically shares the load with the companion supply or takes over if the other unit fails, helping administrators keep storage arrays and surveillance recorders online around the clock.

The wide AC input range of 100 to 240 volts and 47 to 63 hertz frequency support lets the supply operate reliably in data centers, branch offices, and on-site security cabinets worldwide. Inside, high-efficiency circuitry delivers steady voltage to drives, processors, and network interfaces, protecting sensitive data workflows from unexpected shutdowns.

This replacement is a practical spare for IT teams that run mission-critical QNAP deployments. Keeping one on the shelf shortens recovery time after a power fault, reduces downtime during maintenance, and offers peace of mind when uptime is non-negotiable.
