Business SFF Desktop with i7-14700

The HP ProDesk 400 G9 is a small form factor desktop built for office environments. It runs Windows 11 Pro on an Intel Core i7-14700 processor with 20 cores and 28 threads. The system includes 32GB of DDR5 4800 memory and a 512GB SSD. Integrated Intel UHD Graphics 770 drives up to three displays via DisplayPort and HDMI 1.4.

Upgrade from older business PCs

This configuration replaces aging desktops that struggle with modern multitasking or lack DDR5 memory bandwidth. The jump is worth it when daily workloads involve large spreadsheets, multiple browser tabs, or video conferencing while background apps run. The 20-core CPU and fast DDR5 remove bottlenecks common in 4-core or 8-core predecessors without discrete graphics.

Suits standard office deployments

This unit fits buyers who need a compact, quiet tower for general productivity, remote management, and triple-monitor setups. It is not for users who require a dedicated graphics card for 3D rendering, CAD, or gaming. Buyers needing more than 32GB of RAM or multiple high-speed NVMe drives should look at a larger workstation chassis.

Questions about this item

What are the dimensions of the HP ProDesk 400 G9 SFF case?

The chassis measures 10.6 x 3.7 x 12.1 in and weighs 9.25 lbs, so verify desk clearance before placing it.

How do I install the wired keyboard and mouse combo included with the HP ProDesk 400 G9?

Plug both USB connectors into any front or rear Type‑A port; the OS recognises them immediately without driver installation.

Two 16 GB DDR5 4800 modules are installed; the board supports up to 64 GB total, so two 32 GB sticks can replace the pair.
