Dell Pro Tower Plus QBT1250

This Dell Pro Tower Plus QBT1250 is a business desktop built around an Intel Core Ultra 7 265 processor. It ships with Windows 11 Pro, 32GB of DDR5 memory and a 512GB M.2 NVMe SSD. The tower chassis measures 12.8 inches high, 6.1 inches wide and 11.5 inches deep. A 260W power supply, keyboard and mouse are included in the box.

Suitable for offices needing AI Boost and vPro

The configuration suits professionals who want Intel AI Boost capabilities and vPro manageability in a compact tower. It is not for buyers who need discrete graphics performance, wireless connectivity or additional internal storage bays beyond the single M.2 slot.

Intel Core Ultra 7 265 with 5.30 GHz turbo

The decisive specification is the Intel Core Ultra 7 265 CPU, which reaches a 5.30 GHz turbo frequency on a 2.40 GHz base. This determines whether the system meets the compute demands of your workload before you consider memory or storage upgrades.

Questions about this item

How do I upgrade the 32GB DDR5 memory later?

The tower has standard DDR5 DIMM slots; add matching DDR5 modules up to the board limit.

Does the 260W power supply limit sustained turbo on the Core Ultra 7 265?

The 260W unit is sized for the 65W base CPU; extended 5.30GHz boosts may throttle if total draw nears the PSU ceiling.

How loud and hot does the Pro Tower Plus QBT1250 get under all-day load?

Business-class cooling targets quiet office acoustics; expect low fan noise and case temperatures within Dell thermal spec.
