Server-grade 1100 W DC48 V power supply

This unit is built for Dell PowerEdge R620, R720, R730 and R520 servers that require a 48 V DC input. It delivers 1100 W of continuous power in a standard ATX form factor. The design targets data-centre administrators and IT integrators who need reliable, high-efficiency replacement modules.

Hot-swap redundancy and modern standby support

The supply slots directly into the server's redundant power bays and supports hot-swap replacement without downtime. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Zero RPM fan mode keeps the unit silent at light and medium loads.

80 PLUS Gold efficiency with resonant LLC topology

Certified 80 PLUS Gold operation reduces energy waste, heat output and acoustic noise across the load range. Resonant LLC topology with DC-to-DC conversion provides clean, stable rails and minimises coil whine. The platform suits dense rack deployments where power density and quiet running are priorities.

Questions about this item

How does the 1100W capacity handle sustained full-load operation?

The 80 PLUS Gold certification means the unit runs at high efficiency even under continuous 1100W demand, keeping waste heat and power draw lower than non-certified supplies.

Does the fan stay on during an all-day workload?

Zero RPM Fan Mode stops the fan completely at low and medium loads, so the power supply runs silently for long periods until higher loads require active cooling.

Which Dell PowerEdge servers is this E1100D-S0 unit designed to replace?

It is a direct-fit replacement for the R520, R620, R720 and R730 models that use a 48 V DC input.
