Power for PowerEdge servers

This 1100W unit fits Dell PowerEdge R510 R810 R910 T710 models and carries part numbers including L1100A-S0 and 1Y45R+AA. It is a new replacement supply built for those server chassis and accepts worldwide AC input from 100 to 240 volts at 50 to 60 Hz.

Thermals noise and power draw

The supply delivers up to 1100 watts of DC output while drawing from a 100 to 240 volt AC source at 50 to 60 Hz. Internal cooling is handled by the server chassis fans so acoustic and thermal behaviour depends on the host system configuration and workload.

Sustained load behaviour

Under continuous demand the unit maintains its rated 1100 watt output within the specified input range of 100 to 240 volts at 50 to 60 Hz. It is not suited for systems requiring higher wattage or for non-PowerEdge platforms that lack the matching connector and form factor.

Questions about this item

How do I install the L1100A-S0 into a PowerEdge R910 and what step is often missed?

Slide the unit into the power bay until the latch clicks, then tighten the captive retention screw; the screw is the step most people forget.

What maintenance will this 1100W supply need over its service life?

Clean the intake vents and internal fan with compressed air every 3 to 6 months; no user-replaceable parts are inside.

Which limit appears first when the supply runs at full 1100W output continuously?

Thermal protection triggers first; the fan ramps to maximum speed and the unit will shut down if airflow is restricted.
