DELL Precision T5820 Tower Workstation Xeon W-2135 3.7GHz 128GB DDR4 1TB NVMe Quadro P600 desktop PC

Professional workstation for compute-intensive tasks

The Dell Precision T5820 Tower is a mid-tower desktop built around an Intel Xeon W-2135 six-core processor running at 3.70 GHz with a 4.5 GHz turbo frequency. It ships with 128 GB of DDR4 2666 registered ECC memory arranged in four 32 GB modules and a 1 TB PCIe NVMe solid-state drive. An NVIDIA Quadro P600 graphics card with 2 GB GDDR5 and four DisplayPort outputs drives multiple displays. Windows 11 Pro is pre-installed and activated.

Upgrade from consumer desktops or older Xeon towers

This system replaces standard business PCs that lack ECC memory and the 256 GB maximum capacity supported by the eight DDR4 slots. The jump is worth it when workloads demand registered memory integrity, six-core Xeon performance, or a 950 W 80 Plus Gold power supply that can sustain high loads. Buyers who need more than 128 GB of RAM or additional GPU power should look elsewhere.

Build foundation with room for memory and storage

The mid-tower chassis holds the 950 W Gold supply, eight memory slots with four currently populated, and the M.2 NVMe boot drive. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 audio handle networking and sound without extra cards. The Quadro P600 occupies one slot and provides four DisplayPort connections, leaving remaining expansion bays and slots free for additional storage or specialised add-in cards.
