Built for business workloads

The HP ProDesk 400 G9 SFF desktop is powered by an Intel Core i7-14700 processor with 20 cores and 28 threads. It ships with 32GB of DDR5 4800 memory in a 16GB x 2 configuration and a 1TB SSD. Windows 11 Pro is pre-installed, making it ready for professional environments that demand multi-tasking stability and advanced security.

Sustained multi-core throughput

The 2.10GHz base frequency and 5.40GHz turbo frequency combine with 33MB of L3 cache to maintain performance across extended compile, render or data-analysis sessions. Air cooling keeps the small-form-factor chassis within thermal limits without throttling during prolonged loads. Integrated Intel UHD Graphics 770 drives up to three independent 4K displays via rear DisplayPort and HDMI 1.4 outputs.

Upgrades from older SFF fleets

This configuration replaces ageing small-form-factor desktops that struggle with modern memory bandwidth and core counts. The jump is worthwhile when current machines cannot run contemporary business applications smoothly or lack native DDR5 support. It is not suited for buyers who require discrete graphics performance or more than three display outputs.

Questions about this item

How loud is the fan and how much heat does the Intel Core i7-14700 generate when the ProDesk 400 G9 runs all day?

The small form factor uses air cooling to manage the 20-core processor, which has a 2.1 GHz base frequency and can reach 5.4 GHz turbo; the chassis measures 10.6 x 3.7 x 12.1 inches and weighs 9.25 lbs, so airflow is designed for typical office duty cycles.

What display cables or monitors do I already need to use the dual 4K output on this desktop?

The rear panel provides one HDMI 1.4 port and one DisplayPort; you must supply monitors that accept those inputs and the matching cables to drive up to three independent screens.

Will my older USB 2.0 keyboard and mouse work with the front and rear ports on this HP ProDesk 400 G9?

The rear includes two USB Type-A ports at 480 Mbps signaling rate that are backward compatible with USB 2.0 devices, so legacy wired peripherals will function without adapters.
