Mid-Tower Workstation for Business

The HP Z2 G4 is a business-class desktop built around a 6-core Intel Core i5-9500 processor. It ships with Windows 11 Pro and 16 GB of DDR4 memory in a mid-tower chassis. This configuration targets office workloads, multi-monitor productivity and light content creation.

16 GB DDR4 with 128 GB Ceiling

The system includes 16 GB of DDR4-2666 memory installed as two 8 GB modules. The platform supports up to 128 GB total, giving headroom for heavier multitasking or virtual machines. The 2 TB NVMe SSD provides fast boot and application loading. Integrated Intel UHD Graphics 630 drives dual DisplayPort outputs but is not suited for 3D rendering or modern gaming.

500 W 90% Efficient Power Supply

A 500 W unit rated at 90 % efficiency powers the workstation. This capacity supports the included components and modest graphics upgrades. Buyers who need high-end discrete GPUs or many additional drives should verify power headroom before purchasing.

Questions about this item

Will my existing DDR4-2666 memory modules work alongside the installed 16 GB?

Yes, the board supports DDR4-2666 unbuffered DIMMs up to 128 GB total, so additional sticks of the same speed will run without issue.

How can I verify the Intel HD Graphics 630 is driving both DisplayPort outputs correctly?

Open Device Manager in Windows 11 Pro; the adapter should appear as Intel UHD Graphics 630 with two active DisplayPort links shown in the Intel Graphics Command Center.

Does the box include a keyboard and mouse, or must I supply my own?

The system ships with the tower, a 500 W 90 % efficient power supply, and Windows 11 Pro digital licence; keyboard, mouse and monitor are not included.
