DELL Precision 5820 Tower Xeon W-2135 3.7GHz 256GB DDR4 500GB NVMe Quadro P2000 desktop PC

Precision 5820 Tower Xeon Workstation

This Dell Precision 5820 tower workstation is built for professionals who need high core-count CPU performance and large memory capacity in a mid-tower form factor. It ships new with Windows 11 Pro installed and includes a 950 W 80 Plus Gold power supply. The system targets engineers, designers and data analysts running multi-threaded workloads. It does not suit buyers who need a compact chassis or integrated graphics.

256 GB DDR4 2666 Registered ECC Memory

The workstation comes populated with 256 GB of DDR4 2666 registered ECC memory across eight slots, reaching the platform maximum of 256 GB. This capacity lets you keep very large datasets or multiple virtual machines resident without paging. Builders who need more than 256 GB of RAM cannot expand this chassis further. The registered ECC modules also protect data integrity during long compute runs.

Sustained Load Thermal and Power Behaviour

A 950 W 80 Plus Gold certified supply rated at 90 % efficiency delivers stable power to the six-core Xeon W-2135 and Quadro P2000 under continuous load. The 3.7 GHz base clock with 4.5 GHz turbo is maintained by the tower cooling design during extended rendering or simulation tasks. Users relying on passive or low-profile coolers would see throttling in this power envelope. The Quadro P2000 with 5 GB GDDR5 on a 160-bit bus provides steady viewport performance for professional 3D applications.
