1100 W server power supply

This new Dell L1100A-S0 unit delivers 1100 W of AC power to compatible PowerEdge servers. It operates on a 100-240 V input range at 50-60 Hz frequency. The supply uses part number 5G4WK and matches multiple Dell MPNs including 01Y45R and CN-05G4WK.

Compatibility and alternatives

The unit fits Dell PowerEdge R510, R520, R620, R720, R810, R820, R910, R920, R940, T620, T640, T710 and VRTX platforms. It is not for builders who need a different wattage, a redundant form factor for another chassis, or a DC-input variant.

Deciding specification

The single specification that decides fit is the 1100 W output rating combined with the Dell PowerEdge model list. Verify your server model appears in the compatibility list before purchase.

Questions about this item

How much power does the L1100A-S0 draw continuously at full 1100 W load?

The supply accepts 100-240 V at 50-60 Hz and delivers up to 1100 W output; actual AC draw depends on the server load and efficiency at that operating point.

Which Dell server chassis and back-plane connector does this unit slot into?

It is designed for PowerEdge R520, R620, R720, R820, R920, R940, T620, T640 and VRTX systems that use the standard Dell 1100 W redundant PSU form factor.

Will the L1100A-S0 work in my older PowerEdge R510 or R910?

The supplier lists the R510, R810, R910 and T710 as compatible product lines, so the unit fits those chassis electrically and mechanically.
