Workstation for professional workloads

The HP Z2 G4 Mid-Tower is a new business desktop built around an Intel Core i5-9500 6-core processor running at 3.0GHz with 4.4GHz Turbo. It ships with 128GB of DDR4 2666 memory in a 4x32GB configuration and a 4TB PCIe NVMe SSD. An Nvidia Quadro RTX 4000 graphics card with 8GB GDDR6 provides 3x DisplayPort 1.4 and 1x USB-C video outputs. Windows 11 Pro is pre-installed.

Upgrade path from entry desktops

This configuration replaces a standard office PC when the workload needs professional GPU drivers, 128GB of system memory and a multi-terabyte NVMe boot drive. The jump is worth it for CAD, 3D modelling or GPU-accelerated rendering that exceeds integrated graphics and 32GB or 64GB memory limits. Buyers who need ECC memory, dual-socket CPU scaling or more than one high-end GPU should look elsewhere.

Compatibility checklist

Verify that your displays use DisplayPort 1.4 or USB-C video input to match the Quadro RTX 4000 outputs. Confirm the LGA 1151 socket and DDR4 2666 memory specification align with any planned CPU or RAM changes. The 500W 90% efficient power supply and mid-tower chassis set the envelope for future graphics or storage additions.

Questions about this item

What case clearance and power connectors does the Quadro RTX 4000 8GB require in the mid-tower chassis?

The card occupies two full-height slots and draws auxiliary power from the 500W 90% efficient supply via the included PCIe power cables.

Which memory slots are populated by the 128GB DDR4 2666 kit and what is the correct seating order?

Four 32GB unbuffered DIMMs fill all four slots; press each module straight down until the side latches click simultaneously.

When should the 4TB M.2 NVMe SSD be replaced and what capacity does the motherboard support?

Replace the drive when SMART health drops below 90% or write endurance is exhausted; the board accepts a single M.2 NVMe module up to 4TB.
