1100W server power supply

Compatibility and limits

This supply suits administrators maintaining PowerEdge R510, R810, R910 or T710 systems. Builders working on non-Dell platforms or different PowerEdge generations cannot use this unit. It is not for desktop ATX cases or workstations outside the listed compatibility list.

1100W output capacity

The single deciding specification is the 1100W maximum output. Verify that your server configuration requires this exact wattage before purchase. Lower or higher power demands will require a different supply model.

Questions about this item

What server chassis must I already have to install the L1100A-S0 1100W supply?

The unit fits Dell PowerEdge R510, R810, R910 and T710 chassis; it slides into the standard redundant power bay of those models.

Will the supply share load with an older Dell unit already in my R810?

Yes, it supports hot-plug redundant operation alongside another compatible Dell supply so the system balances load automatically.

How can I confirm the L1100A-S0 is delivering 1100W after installation?

The server management console reports each supply’s output in watts; a steady reading near 1100W under load shows it is working as intended.
