Dell KY091 502W server power supply

The Dell KY091 is a 502W power supply designed for the PowerEdge R610 server. It provides replacement or redundant power for that specific platform. System administrators maintaining R610 infrastructure use this unit to restore power capacity.

Hot-plug redundant power architecture

The supply fits the R610 hot-plug bay and works in parallel with a second unit for redundancy. Removing one module while the server runs is supported by the chassis design. Total available power depends on the number of installed units and the server configuration.

502W rated output capacity

The 502W rating defines the maximum power this module can deliver to the R610. Systems with higher total draw require additional modules or a different server platform. Buyers needing more wattage per module cannot use this part.
