Dell PowerEdge T640 — Used & Refurbished (Dell)

Block 1:

How Much Does Dell PowerEdge T640 Cost in 2026?

In 2026, used Dell PowerEdge T640 servers typically range from $1,500 to $15,000, depending on condition and included components. A bare-chassis unit with no storage or redundant PSUs might hit the lower end, while systems with dual Xeon Gold 6230 CPUs, 256GB RAM, and NVMe storage push closer to $12,000–$15,000. Refurbished units from vendors like Caladan Semi average $8,000–$10,000, while "vendor-certified" models (tested for 12-month warranties) cost $10,000–$12,000. Compared to the 2026 OEM list price (~$25,000 for base config), used buys save 40–70%. Caveat: If the server lacks NVMe support (pre-2019 firmware), expect $500–$1,000 extra for compatible storage upgrades.
