Precision 5820 workstation for compute-heavy tasks

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2125 processor running at 4.0 GHz with a 4.5 GHz turbo boost across four cores. It ships with 128 GB of DDR4 2666 registered ECC memory populated across four slots, leaving four additional slots available for expansion up to 256 GB. A 2 TB PCIe NVMe solid-state drive provides primary storage, while an NVIDIA Quadro P2000 graphics card with 5 GB GDDR5 memory drives up to four displays via DisplayPort. Windows 11 Pro is pre-installed on the 64-bit platform.

Sustained load behaviour with 950 W Gold supply

The system is powered by a 950 W 80 Plus Gold certified power supply rated at 90 percent efficiency, designed to deliver stable output during extended rendering or simulation workloads. The Xeon W-2125 maintains its turbo frequency within the thermal envelope of the tower chassis, while registered ECC memory corrects single-bit errors in real time to prevent data corruption during long compute runs. Quadro drivers prioritise OpenGL and compute stability over gaming frame rates, keeping viewport performance consistent across multi-hour sessions.

PCIe Gen3 NVMe and Quadro display limits

The 2 TB NVMe drive operates over a PCIe 3.0 x4 link, capping sequential throughput at the interface maximum rather than the newer Gen4 ceiling. The Quadro P2000 connects through a PCIe 3.0 x16 slot and supports four simultaneous DisplayPort 1.4 outputs, each limited to the bandwidth of that generation. System memory tops out at 256 GB across eight DDR4 slots, so configurations requiring more capacity must move to a different platform.

Questions about this item

How loud and hot does the 950 W 80 Plus Gold power supply get when the Xeon W-2125 runs at 4.5 GHz turbo all day?

The 950 W 80 Plus Gold unit is rated for 90 % efficiency, so waste heat stays low; Dell's workstation thermal design keeps fan noise at typical office levels even under sustained 4.5 GHz loads.

What display cables must I already own to use the Quadro P2000's four DisplayPort outputs?

The card provides four DisplayPort connectors; you need DisplayPort-to-DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters for each monitor you plan to attach.

Will my existing DDR4-2666 ECC RDIMMs work alongside the four 32 GB modules already installed?

Yes — the board has eight DDR4 slots supporting 2666 MHz registered ECC; you can add up to four more identical modules to reach the 256 GB maximum.
