Workstation for professional workflows

The HP Z2 G4 Mid-Tower is a business-class desktop built around an Intel Core i5-9500 6-core processor running at 3.0 GHz with a 4.4 GHz turbo. It ships with 64 GB of DDR4 2666 memory in four 16 GB modules and a 4 TB PCIe NVMe solid-state drive. An NVIDIA Quadro P4000 graphics card with 8 GB of GDDR5 memory provides four DisplayPort 1.4 outputs for multi-display setups. Windows 11 Pro is pre-installed and digitally activated.

Thermals noise and power

The system is powered by a 500 W HP power supply rated at 90 percent efficiency. Integrated Intel I219-LM Gigabit Ethernet and Conexant CX20632 5.1 high-definition audio are onboard. The mid-tower chassis accommodates the installed components and allows airflow for the CPU cooler and the Quadro P4000 blower-style fan under typical office workloads.

Bundled software and accessories

Windows 11 Professional 64-bit is the only software included; no additional applications or recovery media are mentioned. The graphics card supplies four DisplayPort 1.4 connectors so users can attach up to four monitors directly without adapters. Memory can be expanded to 128 GB using the four DDR4 slots if the workload demands more capacity. No monitor keyboard or mouse is included.

Questions about this item

How do I install the 64GB DDR4 2666 memory kit into the four slots?

Power off, open the mid-tower case, align each 16GB DDR4 2666 module with its slot notch, press firmly until both retention clips click, then close the case.

When will the HP 500W 90% efficient power supply need replacement?

The 500W unit typically runs for many years; plan to swap it if voltages drift, fan noise rises, or the system becomes unstable under load.

What thermal limit appears first during long renders on the Quadro P4000 8GB GDDR5?

The GPU hits its temperature target first, causing the card to throttle clocks until the heatsink and case airflow catch up.
