PowerEdge T420 750W hot-plug supply

This Dell 750W hot-plug power supply is built for the PowerEdge T420 server. It delivers 750 watts of power in a proprietary form factor that slides directly into the chassis. System integrators and IT teams use it to replace a failed unit or add redundancy. The hot-plug design lets you swap modules without shutting down the server.

Thermals noise and power draw in normal use

The supply operates within the thermal envelope defined for the PowerEdge T420, drawing up to 750W when the system is fully loaded. Fan speed is managed by the server's integrated cooling logic, so acoustic output varies with workload. In typical operation the unit runs at the efficiency level expected for a 420-class server power supply.
