Workstation for professional visualisation

The HP Z2 G4 mid-tower combines a six-core Intel Core i5-9500 processor with an NVIDIA Quadro RTX 5000 graphics adapter carrying 16GB GDDR6 memory. Sixteen gigabytes of DDR4 2666 RAM and a 2TB NVMe SSD provide a responsive platform for CAD, rendering and simulation workloads. Windows 11 Pro is pre-installed and digitally activated for immediate deployment.

500W 90% efficient supply and quiet operation

A 500W power supply rated at 90% efficiency delivers stable power to the CPU and GPU while limiting waste heat. Integrated Intel I219-LM Gigabit Ethernet and Conexant CX20632 5.1 high-definition audio handle connectivity and sound without add-in cards. The mid-tower chassis uses directed airflow to keep component temperatures low during typical office hours.

Sustained load performance for long renders

Under continuous heavy compute the six-core processor maintains its 3.0GHz base frequency with 4.4GHz turbo headroom available for burst phases. The Quadro RTX 5000 256-bit memory interface supports extended GPU calculations without throttling. Memory capacity can be expanded to 128GB DDR4 if larger datasets demand more RAM headroom.

Questions about this item

How do I install the DDR4 2666 memory modules and what step do people often miss?

Power off the workstation, open the mid-tower case, and insert the 2x 8GB DDR4 2666 modules into the motherboard slots until they click; the step people miss is seating both modules fully so the retention clips lock on each side.

What maintenance or replacement will the Quadro RTX 5000 16GB GDDR6 graphics card need later?

The card uses passive heatsinks cooled by chassis airflow; plan to clean dust from the heatsink fins and case filters every 6-12 months and replace the thermal paste if GPU temperatures rise above normal operating range.

What limit appears first on the 500W 90% efficient power supply under sustained full-load workstation use?

The 500W unit can deliver up to its rated capacity continuously; the first limit is total system power draw reaching 500W, which triggers over-current protection and shuts the workstation down.
