Precision 5820 Xeon workstation

The Dell Precision 5820 tower is a mid-tower workstation built around an Intel Xeon W-2135 six-core processor running at 3.7 GHz with a 4.5 GHz turbo. It ships with 16 GB of DDR4 2666 MHz registered ECC memory across two slots and a 500 GB PCIe NVMe solid-state drive. The Nvidia Quadro P4000 graphics card provides 8 GB of GDDR5 memory and four DisplayPort outputs for multi-monitor setups. Windows 11 Pro is pre-installed and digitally activated.

Sustained compute and graphics throughput

The 950 W 80 Plus Gold power supply delivers 90 percent efficiency to support continuous loads from the Xeon CPU and Quadro GPU without throttling. Eight DIMM slots allow expansion up to 256 GB of DDR4 memory for larger datasets and simulation workloads. The Xeon’s six cores maintain high frequencies during extended rendering or calculation tasks while ECC memory protects data integrity. Quadro drivers are optimised for professional applications such as CAD and visualisation.

Thermals noise and power in daily use

The tower chassis and 950 W Gold-rated supply run cool and quiet during typical office and engineering workloads. Integrated Realtek ALC3234 high-definition audio and Intel i219 gigabit Ethernet handle media and network traffic without adding heat. The Quadro P4000’s blower-style cooler exhausts waste heat directly out the rear, keeping internal temperatures stable. Power draw scales with workload but remains within the supply’s high-efficiency band.

Questions about this item

How loud or hot does the 950 W 80 Plus Gold power supply run when the Xeon W-2135 sustains its 4.5 GHz turbo all day?

The 950 W 80 Plus Gold unit is rated 90 % efficient, so waste heat stays low even under sustained load; Dell’s workstation thermal design keeps fan noise at office-friendly levels during continuous operation.

Which display cables must I already own to use the Quadro P4000’s four DisplayPort outputs?

The card provides four standard DisplayPort connectors, so you need DisplayPort-to-DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters for each monitor you plan to attach.

Can I keep my existing DDR4-2666 ECC modules and add them to the eight slots alongside the factory 16 GB?

Yes, the board accepts up to 256 GB of DDR4-2666 registered ECC across eight slots, so your current sticks can stay installed as long as they match that speed and ECC type.
