HP Z2 G4 Workstation for Professional Workflows

This HP Z2 G4 mid-tower workstation pairs an Intel Core i5-9500 6-core processor with 16GB of DDR4 2666 memory and a 1TB NVMe SSD. The NVIDIA Quadro P4000 8GB GDDR5 graphics card provides four DisplayPort 1.4 outputs for multi-monitor setups. Windows 11 Pro 64-bit is pre-installed and digitally activated. It targets engineers, designers and analysts who need certified professional graphics in a compact business chassis.

Sustained Load Behaviour

The 500W power supply rated at 90% efficiency delivers stable power to the CPU at its 4.4GHz turbo frequency and the Quadro P4000 during extended rendering or simulation tasks. Six cores maintain throughput for multi-threaded workloads such as CAD assemblies or video timelines. The 128GB maximum memory ceiling allows future expansion for larger datasets without replacing the platform.

Thermals Noise and Power in Daily Operation

Mid-tower airflow manages heat from the 500W supply and professional components during typical office hours. Integrated Intel I219-LM Gigabit Ethernet and Conexant CX20632 5.1 audio operate without adding discrete cards that increase fan speed. The 90% efficient supply reduces waste heat and acoustic output compared to lower-rated units. Monitor not included.

Questions about this item

How much fan noise and heat does the 500 W 90% efficient power supply produce when the i5-9500 and Quadro P4000 run all day?

The 500 W power supply is rated at 90% efficiency, so sustained loads on the 6-core i5-9500 and 8 GB Quadro P4000 generate heat proportional to their actual draw rather than the supply's maximum rating.

Which display cables or adapters do I need to connect monitors to the four DisplayPort 1.4 outputs on the Quadro P4000?

The Quadro P4000 provides four DisplayPort 1.4 connectors, so you need monitors with DisplayPort inputs or appropriate DisplayPort-to-HDMI/DVI adapters and cables.

Will my existing DDR4-2666 memory modules work alongside the installed 16 GB kit if I expand toward the 128 GB maximum?

The system uses unbuffered DDR4-2666 memory and supports up to 128 GB, so additional DDR4-2666 modules of the same type can be added to the free slots.
