Support compact storage and infrastructure systems with a 550 W AC power supply engineered for rack-mounted deployment. The AFI airflow profile helps maintain thermal direction within the chassis, which is important in dense equipment rooms where cooling paths must stay consistent across adjacent hardware. This power supply is a strong fit for teams that value exact replacement compatibility and predictable service behavior. In production environments, the right PSU is not just about wattage; it is about matching the platform’s power and airflow expectations so the system continues to operate as designed. For procurement and operations teams, that means fewer surprises during maintenance and a cleaner path to restoring service when a module needs replacement. Choose this PSU when you need a compact AC power module that aligns with rack-based storage deployments and supports the operational discipline expected in enterprise infrastructure.
