Compact workstation for entry CAD and office tasks

The HP EliteDesk 800 G4 Tower combines an Intel Core i3-8300 at 3.7 GHz with an NVIDIA Quadro P400-2GB graphics card. Thirty-two gigabytes of DDR4-2666 memory and a 1 TB hard drive provide capacity for 2D drafting, multi-monitor productivity and general business applications. Windows 11 Pro is pre-installed.

250 W power supply keeps thermals modest

A 250 W internal unit feeds the four-core processor and the low-profile Quadro P400, so heat output stays low in typical office workloads. Fan noise remains quiet during document editing or light model rotation. The chassis draws only the power needed for the installed components.

Single Quadro P400 limits 3D viewport performance

The 2 GB professional GPU handles certified drivers for legacy CAD packages but cannot accelerate large assemblies or modern rendering pipelines. Buyers who need real-time ray tracing, high-poly viewports or GPU compute must choose a workstation with a larger graphics card.

Questions about this item

How do I install the NVIDIA Quadro P400 graphics card in the EliteDesk 800 G4 tower?

The Quadro P400 is already installed in the system; connect your display to the card's video outputs rather than the motherboard ports.

What maintenance or replacement will the 1 TB hard drive need later?

Mechanical hard drives can develop bad sectors or fail over time; plan to replace the 1 TB HDD with a compatible drive and reinstall Windows 11 Pro if it becomes unreliable.

What limit appears first when the 250 W power supply runs the i3-8300 and Quadro P400 under sustained load?

The 250 W internal power supply caps total system draw, so heavy CPU and GPU workloads together will hit that power ceiling before thermal limits become critical.
