Workstation for Professional Workflows

The HP Z2 G4 Mid-Tower Workstation delivers workstation-class performance for engineering, design and content-creation tasks. It pairs an Intel Core i5-9500 six-core processor with 128GB of DDR4 2666 memory and an NVIDIA Quadro P4000 8GB GDDR5 graphics card. Windows 11 Pro is pre-installed for immediate deployment in professional environments.

Standard Mid-Tower Installation

The mid-tower chassis uses industry-standard mounting points and tool-less drive bays for straightforward component access. The 500W 90% efficient power supply provides stable delivery to the Quadro P4000 and all populated memory slots. Builders should verify case clearance for full-length graphics cards and confirm that the LGA 1151 socket matches any planned processor upgrades.

Memory and Storage Headroom

Four 32GB DDR4 modules fill the 128GB maximum supported capacity, leaving no empty slots for further memory expansion. The 2TB PCIe NVMe SSD offers fast boot and application load times with ample space for active projects. Users requiring additional bulk storage must add secondary drives, as no hard drive is included and the M.2 slot is occupied.
