Business tower for multitasking professionals

It ships with 16GB DDR5 memory and a 512GB SSD for quick boot times. Windows 11 Pro is pre-installed and Intel HD Graphics drives multi-display setups.

Sustained workload behaviour

The 20-core CPU with 30MB Intel Smart Cache handles extended multitasking and demanding office applications without relying on short burst speeds alone. DDR5 memory provides faster data processing throughout long sessions. The 260W power supply delivers consistent power to all components during continuous operation.

Thermals noise and power

Dell's Pro chassis uses an advanced cooling system designed for long-lasting performance in business environments. The 260W power supply matches the system's rated draw for efficient operation. No optical drives are fitted, reducing internal heat sources and mechanical noise during normal use.

Questions about this item

How loud and hot does the 260W power supply and 20-core processor get during all-day workloads?

The 260W supply and advanced cooling in the Pro chassis keep the 20-core Intel Core Ultra 7 265 running within thermal limits for sustained business workloads.

Which display cables and monitors must I already own to use the multi-display support?

You need monitors with DisplayPort inputs and matching cables; the integrated Intel HD Graphics drives multiple displays through those ports.

Yes, all four USB 2.0, four USB 3.2 Type-A and two USB 3.2 Type-C ports are backward-compatible with your current USB 2.0 and 3.2 devices.
