Professional CAD Workstation

The HP Z4 G4 Tower is configured for engineering, drafting, 3D modelling and visualisation workloads. An Intel Xeon W-2145 processor with 8 cores at 3.70 GHz delivers sustained performance for professional applications. 32GB of installed memory supports large project files and smooth multitasking. Windows 11 Pro provides modern security and remote desktop features.

Thermals, Noise and Power

A 750W power supply supports the installed components and allows headroom for future add-in cards or storage upgrades. The workstation chassis uses a quiet and efficient cooling design intended for professional environments. ISV certification confirms reliable operation with validated professional software applications. The tower form factor promotes effective airflow during sustained workloads.

Build Integration

The system includes a 512GB SSD and a 2TB HDD, combining responsive solid-state performance with high-capacity storage. The NVIDIA Quadro P2000 graphics card drives workstation-class visualisation tasks. The motherboard provides 8 total memory slots for future expansion beyond the current 32GB. A toolless chassis design allows straightforward access for component upgrades or maintenance.

Questions about this item

How do I install a second M.2 512GB NVMe drive in the Z4 G4, and which step is often missed?

Insert the drive into an open M.2 slot at an angle, press down, and secure it with the screw; the step often missed is enabling the NVMe boot option in the BIOS after installation.

What maintenance will the 750W power supply need after extended use?

Dust the intake vents and fan grill every few months; the 750W unit has no user-serviceable parts, so plan a full replacement only if voltages drift or the fan becomes noisy.

What thermal limit appears first on the Xeon W-2145 during sustained all-core workloads?

The 8-core Xeon W-2145 at 3.70 GHz will hit its package power limit before the 750W supply or chassis airflow become bottlenecks, causing clock speeds to settle below the base frequency.
