HP Z4 G4 Mid-Tower Business Desktop Xeon W-2235 3.8GHz 256GB DDR4 500GB NVMe Quadro P4000 8GB Windows 11 Pro

Professional Xeon W-2235 Workstation

The HP Z4 G4 combines an Intel Xeon W-2235 six-core processor running at 3.8 GHz with 4.6 GHz turbo and 256 GB of DDR4 2933 ECC registered memory. A 500 GB M.2 NVMe drive provides fast boot and project access. NVIDIA Quadro P4000 8 GB GDDR5 graphics with four DisplayPort 1.4 outputs drives professional visualisation workloads. Windows 11 Pro is pre-installed and digitally activated.

Sustained 1000 W Gold Power Delivery

The integrated 1000 W 80 Plus Gold power supply operates at 90 % efficiency to maintain stable voltage during long rendering or simulation sessions. ECC DDR4 2933 memory detects and corrects single-bit errors to prevent data corruption over extended runs. The mid-tower chassis uses tool-less access for airflow paths that keep CPU and GPU temperatures controlled under continuous load. ISV certification validates reliability with leading professional applications.

Tool-less Mid-Tower Expandability

Eight DDR4 slots are populated with 32 GB modules leaving room to reach the 512 GB maximum supported capacity. Multiple PCIe slots and internal drive bays allow additional NVMe, SATA or GPU upgrades without tools. Four DisplayPort 1.4 connectors support multi-monitor setups directly from the Quadro card. Integrated Gigabit Ethernet and high-definition audio handle network and sound without extra cards. Buyers needing more than 500 GB of primary storage or a second graphics card must add components themselves.
