Precision 5820 workstation for professional

The Dell Precision 5820 Tower is a mid-tower desktop built around an Intel Xeon W-2255 processor with 10 cores running at 3.7 GHz and a 4.7 GHz turbo frequency. It ships with 128 GB of DDR4 2933 MHz registered ECC memory across four 32 GB modules and a 1 TB PCIe NVMe solid-state drive. The Nvidia Quadro P4000 graphics card provides 8 GB of GDDR5 memory and four DisplayPort outputs for multi-monitor configurations. Windows 11 Pro is pre-installed and digitally activated.

Sustained multi-core performance with ECC memory

The 10-core Xeon W-2255 maintains high clock speeds under continuous load, supported by the 950 W 80 Plus Gold power supply rated at 90 percent efficiency. Registered ECC DDR4 memory detects and corrects single-bit errors, preserving data integrity during long rendering, simulation or compute jobs. The 1 TB NVMe drive delivers consistent throughput for large project files and scratch disks. Quadro P4000 drivers are optimised for ISV-certified applications, keeping frame rates stable across extended sessions.

Thermals, acoustics and power in daily use

The tower chassis uses directed airflow to cool the CPU, GPU and memory without excessive fan noise during typical workloads. The 950 W Gold-certified supply operates efficiently at normal loads, reducing waste heat and acoustic output. Integrated Realtek ALC3234 audio and Intel i219 Gigabit Ethernet add minimal thermal contribution. The system stays within its thermal envelope for standard business and creative tasks without requiring additional cooling measures.

Questions about this item

How much heat and power does the 950 W 80 Plus Gold supply draw when the Xeon W-2255 runs at 4.7 GHz all day?

The 950 W 80 Plus Gold unit is rated at 90 % efficiency, so sustained full-load output will draw roughly 1 050 W from the wall and exhaust a corresponding amount of heat.

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

The card provides four DisplayPort connectors, so you need four DisplayPort cables or suitable adapters for your monitors.

Will the registered ECC DDR4 2933 modules work in a consumer board that only supports unbuffered DDR4 2666?

No, the 128 GB kit uses registered ECC DDR4 2933 DIMMs which require a workstation chipset and will not function in standard consumer motherboards.
