Workstation for Professional Workflows

The HP Z2 G4 Mid-Tower is a new business desktop built around an Intel Core i5-9500 processor running at 3.0 GHz with a 4.4 GHz turbo boost. It ships with 32 GB of DDR4 2666 memory in a four-by-eight configuration and a 1 TB NVMe solid-state drive. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Suited for Office and Light Creative Tasks

This system fits users who need a reliable tower for productivity applications, multi-monitor setups via dual DisplayPort outputs, and fast boot times from NVMe storage. It is not intended for buyers who require a discrete graphics card for 3D rendering or GPU-accelerated workloads, nor for those needing ECC memory support.

32 GB DDR4 2666 Memory Installed

The workstation arrives with 32 GB of unbuffered DDR4 2666 RAM, expandable to a maximum of 128 GB across its available slots. This capacity determines whether the machine can handle your current multitasking demands or if a higher-density kit must be sourced before deployment.

Questions about this item

How long can the i5-9500 sustain its 4.4 GHz turbo before thermal limits throttle it?

The 500 W 90% efficient power supply and mid-tower airflow are designed to handle sustained loads, but exact turbo duration depends on ambient temperature and workload mix.

What noise and heat levels should I expect when the workstation runs all day?

The 500 W 90% efficient supply and integrated Intel UHD 630 graphics keep power draw modest; fan speed scales with CPU temperature, so acoustics stay typical for a business mid-tower under continuous use.

Which display cables do I need to connect monitors to the dual DisplayPort outputs?

The integrated Intel UHD 630 provides two DisplayPort connectors, so you will need DisplayPort cables or DisplayPort-to-HDMI adapters for each monitor you attach.
