HP Z2 G4 Workstation Overview

This HP Z2 G4 mid-tower workstation is built around an Intel Core i9-9900K 8-core processor running at 3.6GHz with a 5.0GHz turbo. It ships with 16GB of DDR4 2666 memory, a 2TB NVMe SSD and an NVIDIA Quadro P1000 4GB GDDR5 graphics card. The system targets professionals who need reliable compute and certified drivers for CAD, DCC or simulation workloads. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Build Integration and Expansion

The LGA 1151 platform supports up to 128GB of DDR4 memory across four slots, leaving room to double or quadruple the installed capacity. The 2TB M.2 NVMe drive occupies one slot; additional M.2 or 2.5-inch bays are available for extra storage. A 500W 90% efficient power supply feeds the CPU, Quadro P1000 and peripherals. Four mini-DisplayPort 1.4 outputs drive multiple displays without adapters. Integrated I219-LM Gigabit Ethernet and 5.1 high-definition audio handle networking and sound without extra cards.

Sustained Load Behaviour

The 8-core i9-9900K maintains high frequencies across all cores during long renders or simulations, supported by the workstation-class thermal design. Quadro P1000 drivers are optimised for stability in ISV applications over extended sessions rather than short benchmark runs. DDR4 2666 bandwidth feeds the CPU consistently, while the NVMe SSD keeps project assets streaming without throttling. The 500W power supply delivers steady current to the GPU and CPU under continuous professional workloads.

Questions about this item

Will the 500W power supply sustain the i9-9900K at 5.0GHz turbo under long renders?

The 500W unit is rated at 90% efficiency and powers the i9-9900K, Quadro P1000, 16GB DDR4 and 2TB NVMe SSD within its designed envelope.

How loud does the mid-tower get when the Quadro P1000 and i9-9900K run all day?

HP engineers the Z2 G4 for quiet office operation; the 500W supply and system fans are tuned for low acoustic output under sustained professional workloads.

Does the Quadro P1000 require extra power cables or can it run from the motherboard?

The Quadro P1000 draws all power from the PCIe slot; no auxiliary connectors are needed from the 500W supply.
