Compatible Dell server power supply

This new 1100 watt unit replaces part numbers AA27120L, 5G4WK, Y1MGX and 02RN7 in Dell PowerEdge R620, R720, R730 and R520 servers. It delivers 48 volt DC output for direct integration into those chassis. The unit is built for administrators who need a direct-fit replacement without adapter cables.

Thermal and power behaviour

The supply operates from a 48 volt DC source and provides up to 1100 watts to the server backplane. Internal fan speed scales with load to maintain safe component temperatures inside the 1U or 2U form factor. Acoustic output rises under heavy draw but remains within typical data-centre limits. No efficiency rating or idle power figure is published.

Questions about this item

How do I install the E1100D-S0 into a Dell R620, and which step is often missed?

Slide the unit firmly into the chassis bay until the latch clicks, then verify the DC 48V input connector is fully seated; the click is the step most people skip.

What maintenance will the E1100D-S0 need during its service life in a Dell R720?

Clean the intake vents every few months to prevent dust build-up on the internal fan; the unit has no user-serviceable parts, so replacement is only required if the supply fails.
