1100 Watt Power Supplies
Key takeaways
- 486 listings match this collection right now.
- 1100 watt units still deliver their full rated output across the standard 100 to 240 volt range, below the threshold where the platform requires 200 to 240 volts.
- At 120 volts, an 1100 watt module draws current close to the limit of a standard C13/C14 rack connector, pushing facilities toward a 208 or 240 volt circuit.
- A single 1100 watt module can run a fully configured two-socket chassis alone, but pairing two turns the same bay into an N+1 redundant configuration rather than added capacity.
1100 watts is the Dell PowerEdge class for heavily configured two-socket servers: full drive bays, high-TDP processors or a GPU. The same wattage appears from Lite-On and Delta as the manufacturer part behind the Dell number.

How to choose power supplies
Server supplies are platform-specific: the part number ties to a chassis family and a wattage class, and a redundant pair must be the same model. Match the wattage class already installed, the input (100 to 240 V AC or 48 V DC) and the efficiency grade if the platform enforces one. Desktop supplies in this category follow ATX form factors instead.
