Precision T5820 workstation

The Dell Precision T5820 is a mid-tower workstation built around an Intel Xeon W-2135 six-core processor running at 3.7 GHz with a 4.5 GHz turbo. It ships with 64 GB of DDR4 2666 registered ECC memory in four 16 GB modules and a 1 TB PCIe NVMe solid-state drive. An NVIDIA Quadro P4000 graphics card with 8 GB GDDR5 memory provides four DisplayPort outputs. Windows 11 Pro is pre-installed.

Build integration

The LGA 2066 motherboard offers eight DDR4 slots, allowing memory expansion up to 256 GB. The Quadro P4000 occupies a double-width PCIe slot and drives up to four displays without additional adapters. A 950 W 80 Plus Gold power supply delivers 90 % efficiency and includes the connectors required by the installed graphics card. Integrated Intel i219 gigabit Ethernet and Realtek ALC3234 audio are available on the rear I/O panel.

Thermals and power

The tower chassis uses Dell's internal airflow design to cool the Xeon processor and Quadro P4000 under sustained workloads. The 950 W Gold-rated supply runs at high efficiency, reducing waste heat and keeping fan speeds lower during typical professional tasks. Registered ECC memory operates at standard DDR4 2666 voltage, contributing to stable thermal behaviour. Noise levels remain consistent with business-class workstation expectations.

Questions about this item

Will the 950-watt 80 Plus Gold power supply sustain the Xeon W-2135 at 4.5 GHz turbo without throttling?

The 950 W 80 Plus Gold unit delivers 90 % efficiency and is rated for the full platform power draw, so the 6-core Xeon can hold its 4.5 GHz turbo under sustained loads.

How loud does the tower get when the Quadro P4000 and Xeon run flat-out for hours?

Dell's thermal design uses variable-speed fans that ramp quietly at idle and rise to a moderate airflow under full GPU and CPU load, staying within typical workstation acoustic limits.

Does the Quadro P4000 need any extra power cables beyond what the 950 W PSU provides?

The 950 W supply includes the required PCIe connectors for the Quadro P4000, so no additional cables or adapters are needed.
