Dell 495W Power Supply for PowerEdge R640, R740, R740xd — VKDD2

Offered here is a 495W power supply, identified by Dell part number VKDD2.

With two supplies on separate circuits, the server keeps running if one feed is lost. Hot-swap supplies can be changed with the server running, as long as the other unit carries the load. The server’s power budget depends on its processors, drives and cards, so confirm the wattage suits the build. Compatible systems named for this part: PowerEdge R640, R740 and R740xd. That spans three server models, so one spare can cover a mixed estate of them. Where a server takes two supplies, keep both at the same wattage; mixed ratings are not supported. Dell part numbers identify the exact revision, which matters more than the description when several look-alike parts exist. Server power supplies report their health to the management controller, so a failing unit shows up in the hardware log. Check VKDD2 against the service configuration of your Dell system before ordering.

Condition is certified refurbished, and each part is inspected, bench-tested and checked in Johannesburg.
