MikroTik DPS-550AB-36G 550W Replacement Hot-Swap PSU

The MikroTik DPS-550AB-36G is not a generic PSU — it is the purpose-designed replacement power supply for the ROSE Data Server (RDS2216), engineered specifically to match the RDS2216's energy-efficient architecture and low heat-output operating profile. Using an incorrect or generic PSU in the RDS2216 risks mismatched power delivery, excess heat, and potential damage to the server chassis or NVMe drives. The DPS-550AB-36G is the only confirmed compatible replacement.

The hot-swap design is the operational story. In a production storage server environment, a failing or failed PSU should never require a server shutdown. The DPS-550AB-36G slides out and back in while the server continues running — no graceful shutdown, no data flush, no service window required. For data centre operators, MSPs, and IT teams managing storage infrastructure for clients or internal business operations, this is the difference between a 30-second swap and a scheduled maintenance window.

At 12V / 550W output, the DPS-550AB-36G delivers the correct power profile for the RDS2216 chassis under full NVMe drive load. The ROSE Data Server is designed around a low power consumption, reduced heat output philosophy — and the DPS-550AB-36G is matched to that design. Substituting a higher-wattage PSU does not improve performance and may introduce unnecessary heat into the chassis.

MTBF of approximately 200,000 hours at 25°C aligns with the ROSE Data Server platform's own reliability target — ensuring the PSU is not the weakest link in the system's uptime expectations.
