Hot-Plug Power Supplies
Key takeaways
- 1,836 listings match this collection right now.
- A status LED on the module face, green when healthy and amber or red on a fault, tells a technician when it is safe to pull.
- Each hot-plug module carries its own fan, pulling air through its own path independent of the chassis fans, which is why it can be swapped without powering the system down.
- A hot-plug module releases with a spring latch or lever, no screwdriver needed, while a fixed PSU of the same wattage is screwed into the chassis and needs a full power-down to remove.
Hot-plug modules slide out of the chassis rear without powering the system down, provided the second module carries the load. This collection holds the modules named as hot-plug or hot-swap in the catalogue; the redundant collection is the broader set.

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.
