Workstation Core & Memory

The HP Z2 G4 Mid-Tower Workstation is built for professionals who need reliable compute power in a standard desktop form factor. A 6-core Intel Core i5-9500 running at 3.0 GHz with 4.4 GHz turbo drives everyday workloads, while 32 GB of DDR4 2666 MHz memory across four slots handles multitasking and larger datasets.

Storage & Graphics Bundle

A 4 TB PCIe NVMe solid-state drive provides ample high-speed capacity for operating system, applications and active project files without mechanical drives. Integrated Intel UHD Graphics 630 delivers dual DisplayPort video output for two monitors, and onboard 5.1 high-definition audio supports basic multimedia needs.

Compatibility Checklist

Verify that your displays use DisplayPort inputs or that you have suitable adapters for other interfaces. The LGA 1151 socket and 128 GB maximum memory limit define future processor and RAM upgrade paths. A 500 W 90 % efficient power supply is installed, so confirm it meets the demands of any discrete graphics card you may add later.

Questions about this item

Will the 500W 90% efficient power supply need replacement if I add a dedicated graphics card later?

The 500W unit leaves limited headroom for high-end GPUs; a larger PSU may be required depending on the card's power draw.

Does the Intel HD Graphics 630 throttle under sustained 4K video workloads?

Integrated graphics share system memory and have no dedicated VRAM, so prolonged heavy encoding will hit thermal and bandwidth limits first.

How loud is the mid-tower chassis when the i5-9500 runs at 4.4GHz Turbo all day?

The stock cooler and case fans stay relatively quiet at idle but become audible under continuous maximum turbo load.
