DELL W8R3C 750W 80+ server power supply

Dell 750W redundant PSU

The Dell W8R3C is a 750 watt hot-plug power supply built for Dell PowerEdge servers. It uses a common-slot design that supports tool-free installation and power discovery services. The unit delivers 94 percent efficiency under the 80 Plus Platinum rating. It is intended for data-centre administrators replacing or adding redundant power in compatible Dell systems.

Compatibility check

Verify that your server model appears in the supported list: R730XD, R730, R630, T630, T430 or R640. The power supply accepts 100 to 240 volt input at 50 or 60 hertz. Do not mix this unit with power supplies of a different wattage or efficiency class in the same chassis. Firmware updates will power the managed system off for three to ten minutes before an automatic reboot.

Hot-plug and efficiency benefits

The hot-plug capability lets technicians swap the module without shutting down the host server. Common-slot architecture reduces trapped power capacity and simplifies spares inventory across multiple Dell platforms. Power discovery via the blue plug enables the system to identify the supply and manage load balancing. These features lower energy costs and minimise downtime during maintenance.
