Precision 5820 Xeon workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2145 processor with eight cores running at 3.7 GHz and a 4.5 GHz turbo frequency. It ships with 16 GB of DDR4 2666 registered ECC memory across eight slots, a 500 GB NVMe SSD and an Nvidia Quadro P4000 graphics card with 8 GB GDDR5. Windows 11 Pro is pre-installed for professional workflows.

Thermals and 950 W Gold supply

A Dell 950 W power supply rated 80 Plus Gold at 90 % efficiency delivers stable power to the CPU, GPU and memory subsystem. The tower chassis uses directed airflow to manage heat from the Xeon processor and Quadro card during sustained compute or rendering tasks. Acoustic output remains at typical workstation levels under normal office loads.

Quad DisplayPort and expandability

The Quadro P4000 provides four DisplayPort outputs for multi-monitor configurations without adapters. Eight DIMM slots support up to 256 GB of DDR4 ECC memory for larger datasets. The LGA 2066 platform and mid-tower form factor allow additional storage or add-in cards, while the single NVMe drive leaves M.2 capacity for future expansion. Buyers needing more than 500 GB of fast storage or a second graphics card should plan upgrades.

Questions about this item

How do I install the Xeon W-2145 processor into the LGA 2066 socket without bending pins?

Align the gold triangle on the CPU with the socket corner marker, lower it straight down without force, then close the retention lever until it clicks; the 8-core chip seats in one orientation only.

When will the 16GB DDR4 2666 registered ECC memory need expansion for larger workloads?

The board offers eight slots and supports up to 256 GB total; add matched RDIMMs in pairs when projects exceed the factory 2x 8 GB configuration.

At what point does the 950 W 80 Plus Gold power supply become the limiting factor during sustained heavy compute?

Continuous draws approaching 90 % of the 950 W rating — such as full CPU turbo plus the Quadro P4000 at peak — leave minimal headroom for additional drives or cards.
