Business desktop with Intel Core Ultra 7 265

The Dell Pro Tower Plus QBT1250 is a tower form-factor PC built for business and mainstream workloads. It ships with Windows 11 Pro and includes a keyboard and mouse. An Intel Core Ultra 7 265 processor provides a 2.40 GHz base frequency and a 5.30 GHz turbo frequency. Integrated Intel Graphics handles display output.

Suits office teams needing AI Boost

This system targets users who want on-device AI acceleration and a built-in DVD-RAM/±R/±RW drive for legacy media. Buyers requiring discrete graphics performance for rendering or gaming should consider other configurations. The single Gigabit Ethernet port supports wired networks only, so environments needing Wi-Fi must add a separate adapter.

512 GB M.2 NVMe SSD defines storage capacity

The boot drive is a 512 GB M.2 NVMe solid-state drive. No additional internal storage is mentioned in the specifications. Customers who need more space for large datasets or local backups will have to add drives themselves if the chassis and motherboard allow.

Questions about this item

Should I pick the 16GB DDR5 configuration or add more memory later?

The system ships with 16GB DDR5 installed; the tower form factor provides internal slots for future expansion if workloads demand more capacity.

What does the Intel Core Ultra 7 265 turbo of 5.30 GHz deliver in daily use?

The 5.30 GHz turbo lets the 265 processor accelerate single-threaded tasks such as spreadsheet recalculation or app launch, while the 2.40 GHz base sustains steady multi-core throughput.

How does the M.2 NVMe interface affect real-world drive speed?

The 512GB SSD uses an M.2 NVMe connection, so read and write throughput is determined by the platform's PCIe lane allocation rather than a legacy interface bottleneck.
