Dell PowerEdge 495 W Redundant Module

This Dell PowerEdge power supply delivers up to 495 watts of redundant power for compatible server chassis. The hot-swap design allows replacement without shutting down the host, supporting continuous operation in mission-critical environments. It accepts a universal input range of 100 to 240 volts at 50 or 60 hertz.

80 Plus Platinum Efficiency Under Load

Rated at 80 Plus Platinum, the unit maintains high conversion efficiency across typical server load profiles rather than only at peak output. Redundant architecture shares current between modules, reducing thermal stress on each supply during sustained operation. The wide input voltage window accommodates fluctuating mains conditions found in data-centre deployments.

Hot-Swap Build for Rack Maintenance

A hot-swap connector and latch mechanism enable tool-less removal while the system remains powered, minimising downtime during maintenance windows. Redundant configuration means a single module failure does not interrupt service, allowing scheduled replacement. Dell manufacturing standards and rigorous testing ensure consistent reliability for enterprise infrastructure.

Questions about this item

How much heat and noise should I expect from the 495 W 80 Plus Platinum unit when it runs continuously?

The 80 Plus Platinum rating means the supply operates at high efficiency across typical loads, so less energy is wasted as heat and the cooling fan can run at lower speeds during all-day operation.

Which Dell PowerEdge chassis and backplane must I already have for this hot-swap module to connect and lock in place?

This VKDD2 module is designed for Dell PowerEdge servers that accept a 495 W redundant hot-swap power supply; the chassis must provide the matching bay and power backplane for the unit to seat and latch correctly.

Will the 100-240 V, 50/60 Hz input let this supply share a rack PDU with older Dell servers that use different wattage modules?

Yes, the wide 100-240 V input range and 50/60 Hz tolerance match the AC specifications of many legacy Dell PowerEdge platforms, allowing mixed-wattage modules to draw power from the same PDU.
