495W to 1100W hot-plug supplies verified against your service tag before they ship.
Dell built the R620 with three hot-plug power supply options: 495W, 750W and 1100W. Which one your server needs depends on processor wattage, memory count and drive load; dual-CPU builds with full DIMM slots generally want 750W or above. In a redundant configuration both supplies must be the same wattage; iDRAC flags a mismatched pair and Dell does not support running one. The same 12th-generation supply family appears across several PowerEdge rack models, but small part-number variations matter, so match on the Dell part number printed on the PSU label rather than wattage alone. Failed units swap hot with no shutdown. If the label is unreadable, send us your service tag and we will pull the original configuration and match the correct replacement free.
Many 12th-generation hot-plug supplies are shared across Dell's rack models of that era, so some part numbers cross over. Verify the exact Dell part number rather than swapping on wattage alone; we will confirm compatibility against your R620 free.
No. Dell requires both supplies in a redundant configuration to be the same wattage, and the system reports a fault on a mismatched pair. Match the replacement to the surviving unit.
The Dell part number and wattage are printed on the PSU label, and iDRAC reports the installed wattage without opening the rack. If you only have the service tag, send it over and we will pull the factory configuration.
