DELL Precision 5820 Tower Xeon W-2155 10 Core 256GB DDR4 1TB NVMe Quadro P4000 Windows 11 Pro

Precision 5820 Tower for professional workloads

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2155 processor with 10 cores running at 3.3 GHz and a 4.5 GHz turbo frequency. It ships with 256 GB of DDR4 2666 registered ECC memory across eight slots and a 1 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 memory drives up to four DisplayPort monitors. Windows 11 Pro 64-bit is pre-installed and digitally activated.

950 W Gold power supply and Quadro connectivity

A 950 watt 80 Plus Gold certified power supply rated at 90 percent efficiency delivers stable power to the CPU, memory and graphics card. The Quadro P4000 provides four DisplayPort outputs for multi-monitor configurations without adapters. Wired networking is handled by an Intel i219 Gigabit Ethernet controller, while integrated Realtek ALC3234 high-definition audio supports headset and speaker connections. The black chassis follows Dell's Precision tool-less design for internal access.

Upgrades from entry workstations

This system replaces lesser-equipped desktops when applications demand 256 GB of ECC memory and a certified professional GPU. The Xeon W-2155 platform suits rendering, simulation and large-dataset analysis that exceed consumer-grade core counts and memory limits. Buyers who need more than four display outputs or a different GPU architecture should verify compatibility before purchase. The 1 TB NVMe drive covers the operating system and active projects; additional storage bays are available for expansion.
