DELL SC4020 Server Power Supply 580W TDPS-580AB D Y5W2H

Dell Compellent SC4020 Power Supply

This 580 W unit is built for the Dell Compellent SC4020 storage array. It delivers the rated output required by that platform and carries Dell part numbers Y5W2H, CN-0Y5W2H and 0Y5W2H. The supply is sold new and matches the original OEM specification.

Hot-plug redundancy for the SC4020 chassis

The module slides into the SC4020 power bay without tools and works alongside a second supply for N+1 redundancy. It draws AC input from the rack PDU and feeds the array’s internal backplane, freeing the administrator from external adapters or cabling changes.

Steady 580 W under continuous array load

The supply maintains its full rated output during sustained drive rebuilds, replication streams and controller failover events. Thermal regulation keeps output stable without throttling, and the hot-swap design allows replacement while the storage array remains online.
