Mid-Tower Workstation for Professional Workloads

The HP Z2 G4 Mid-Tower Workstation delivers a 6-core Intel Core i5-9500 processor running at 3.0GHz with a 4.4GHz turbo frequency. It includes 32GB of DDR4 2666MHz memory arranged as four 8GB modules. A 1TB PCIe NVMe solid-state drive provides fast storage for operating system and project files. The system targets professionals who need certified application stability in a standard mid-tower form factor.

Quadro P5000 16GB Multi-Display Graphics

The NVIDIA Quadro P5000 adds 16GB of GDDR5X memory on a 256-bit bus for GPU-accelerated tasks such as 3D rendering, CAD and video editing. Its output panel supplies four DisplayPort 1.4 connectors and one dual-link DVI-D port, allowing up to five monitors to be driven simultaneously without additional adapters. Windows 11 Pro is pre-installed and digitally activated so the workstation is ready for immediate deployment.

500W 90% Efficient Power Supply and Connectivity

A 500-watt power supply rated at 90% efficiency powers the components while leaving headroom for the Quadro P5000. Integrated Intel I219-LM Gigabit Ethernet provides wired network connectivity at 10/100/1000 speeds. Conexant CX20632 5.1 high-definition audio supports multi-channel output for content review. The motherboard supports up to 128GB of DDR4 memory across four slots for future expansion.

Questions about this item

Can the 32 GB DDR4 2666 memory be expanded later, and what is the maximum supported?

The board supports up to 128 GB of DDR4 2666 memory across four slots, so the current 4 × 8 GB configuration can be increased by adding or replacing modules.

Which component is likely to hit its limit first during long rendering sessions on the Quadro P5000?

The 16 GB GDDR5X frame buffer on the Quadro P5000 will fill before the 32 GB system memory or the 500 W power supply becomes a bottleneck in sustained GPU workloads.

How much heat and fan noise should I expect from the 500 W 90 % efficient supply when the system runs all day?

At 90 % efficiency the 500 W supply wastes roughly 50 W as heat under full load, so the chassis fans run at moderate speed and the unit stays noticeably warm but not loud during continuous operation.
