DELL Precision 5820 Tower Workstation Xeon W-2245 256GB DDR4 1TB NVMe Quadro P5000

Professional tower workstation

The Dell Precision 5820 Tower is a mid-tower desktop built around an Intel Xeon W-2245 processor with eight cores running at 3.90GHz and a 4.7GHz turbo frequency. It targets engineers, designers and analysts who need certified stability for simulation, rendering or large dataset workloads. The system ships with Windows 11 Pro pre-installed and no monitor included.

Memory ceiling and graphics expandability

The board provides eight DDR4 slots populated with 256GB of 2933MHz registered ECC memory, reaching the platform maximum. A single 1TB PCIe NVMe drive handles boot and active projects, leaving additional M.2 and drive bays free for capacity growth. The Quadro P5000 adds 16GB GDDR5X video memory and four DisplayPort outputs, while the 950W 80 Plus Gold supply leaves headroom for further add-in cards.

Sustained thermal and power behaviour

The 950 watt 80 Plus Gold certified power supply operates at 90% efficiency, feeding the Xeon and Quadro under continuous load without throttling. Registered ECC memory corrects single-bit errors in real time, preserving data integrity during multi-hour compute runs. The mid-tower chassis and Dell thermal design maintain stable clock speeds across extended rendering or simulation sessions.
