HP Z2 G4 Mid-Tower Workstation

The HP Z2 G4 mid-tower workstation is built for professionals who need reliable performance in CAD, 3D modelling or multi-application workflows. It pairs a 6-core Intel Core i5-9500 processor with 128 GB of DDR4 2666 memory and a 1 TB NVMe SSD. The NVIDIA Quadro P600 2 GB GDDR5 graphics card drives up to four displays via mDP 1.4 outputs. Windows 11 Pro is pre-installed and digitally activated.

Thermals Noise and 500 W Power Supply

A 500 W power supply rated at 90 % efficiency delivers stable power to the CPU, GPU and memory under sustained loads. The mid-tower chassis provides room for airflow around the components, helping to keep operating temperatures in check during extended rendering or simulation sessions. Integrated Intel I219-LM Gigabit Ethernet and Conexant CX20632 5.1 high-definition audio add connectivity without adding heat-generating expansion cards.

Build Integration Four mDP Outputs and M.2 NVMe

Four mini DisplayPort 1.4 connectors free up PCIe slots that would otherwise be needed for additional video cards. The M.2 NVMe drive occupies a dedicated slot on the motherboard, leaving 2.5-inch and 3.5-inch bays available for future storage upgrades. The LGA 1151 socket and four DIMM slots are fully populated with 4×32 GB modules, so memory expansion would require module replacement rather than simple addition.

Questions about this item

How do I install the four 32 GB DDR4 2666 modules so the system sees all 128 GB?

Power off, open the mid-tower side panel, and seat each module fully in the four DIMM slots until the retention clips click; the platform maximum is 128 GB and the kit fills it completely.

When will the 500 W 90 % efficient power supply or the Quadro P600 2 GB GDDR5 card typically need replacement?

The 500 W unit is rated for continuous operation at 90 % efficiency; the Quadro P600 2 GB GDDR5 has no moving parts, so plan PSU replacement after 5–7 years of heavy daily use.

What thermal or power limit appears first when the i5-9500 runs at 4.4 GHz turbo under sustained load?

The 500 W 90 % efficient power supply and the mid-tower airflow set the practical ceiling; the CPU will throttle to stay within the 500 W budget before the 4.4 GHz turbo can be held indefinitely.
