Business SFF Desktop

The HP ProDesk 400 G9 SFF is a new business desktop powered by an Intel Core i7-14700 processor with 20 cores and 28 threads. It ships with Windows 11 Pro, 32GB of DDR5 4800 memory in a 16GB x 2 configuration, and a 1TB SSD. Integrated Intel UHD Graphics 770 drives up to three independent displays via rear HDMI 1.4 and DisplayPort outputs. A wired keyboard and mouse combo is included.

Setup Checklist

Verify that your monitors accept HDMI 1.4 or DisplayPort input for the triple-display capability. The chassis provides front USB Type-C and Type-A ports at 10Gbps signaling plus rear USB Type-A at 5Gbps and 480Mbps. Built-in Wi-Fi 5 and RJ-45 Ethernet handle networking. Air cooling is used, so ensure adequate airflow in the intended location.

Fit and Alternatives

This system suits offices needing a compact, multi-monitor workstation with strong multi-threaded performance out of the box. Buyers who require discrete graphics for 3D rendering or GPU compute should consider other configurations. Those needing more than 32GB of memory or additional internal drive bays will find the SFF layout limiting.

Questions about this item

Does the box include a keyboard and mouse, or do I need to buy them separately?

A wired keyboard and mouse combo is included in the package, so no separate purchase is required for basic input devices.

The listing mentions 32 GB DDR5 4800 as 16 GB × 2 — does that fill both slots or leave room for more?

The two 16 GB modules occupy two slots; the platform supports up to 64 GB, so two additional slots remain available for future expansion.

With Intel UHD Graphics 770 and one HDMI 1.4 plus one DisplayPort, can I really run three 4K monitors at once?

The rear HDMI 1.4 and DisplayPort can drive two 4K displays; a third monitor requires a USB-C adapter or dock connected to the front 10 Gbps Type-C port.
