Dell Power Supplies
Genuine Dell power supplies for PowerEdge servers and Precision workstations — matched by Dell part number to the platform they power and load-tested before shipping.
Dell PSU — Power Supplies for PowerEdge Servers & Precision Workstations
Every Dell PSU here is a genuine Dell power supply unit: load-tested before it ships and matched by part number to the platform it powers — hot-swap modules for Dell PowerEdge servers up to 2700W, plus internal supplies for Precision workstation towers. A failed supply or an empty redundancy bay is a same-week fix, not a support ticket. Need HPE, Lenovo, or Supermicro instead? See the full power supplies department.
Matching a Dell Server Power Supply
- Part number first: Dell PSUs are platform-specific modules — read the part number off the installed unit’s label, or send us the server model and wattage.
- Common wattages: 495W and 750W cover most R530/R630/R730 and R640/R740 configurations; 1100W–1600W suit GPU and high-drive-count builds; 2000W+ feed dense chassis.
- Redundant pairs match: both bays want the same wattage and efficiency rating — mixing sizes forfeits redundancy on most PowerEdge platforms.
- Hot-plug means no downtime: on a redundant server, a failed module swaps in service — no shutdown required.
Workstation supplies are model-specific too: Precision towers take their own form factors, so match the exact model rather than generic ATX sizing. Not sure which Dell power supply your machine takes? Send us the model or service tag and we will confirm the right unit before you order.

Quick Answers: Buying Dell PSUs from PCSP
How do I find the right Dell PSU for my PowerEdge server?
Pull the installed supply — hot-swap modules come out without tools — and read the Dell part number off the label, or simply send us the server model and installed wattage. Our listings name the compatible PowerEdge models on every unit, and we confirm fit before shipping.
Can I mix wattages in a redundant PowerEdge server?
Do not plan on it. PowerEdge platforms expect both bays to hold the same wattage and efficiency rating; a mismatched pair is either refused outright or quietly loses redundancy. Buy a matched pair, or match the module already installed.
Are these genuine Dell power supply units?
Yes — OEM Dell modules with their original part numbers listed, not generic substitutes. Every unit is load-tested before listing, and DOA or non-conforming supplies are covered by 90-day returns at our expense.
Can I upgrade to a higher-wattage Dell power supply?
Usually, yes — as long as your chassis supports that module family and you upgrade both bays together. It is the standard move when added GPUs or extra drives push past the original power budget. Tell us your configuration and we will size it.
