Our take on the HP Pro Mini 400 G9 Desktop Computer

The HP Pro Mini 400 G9 is a small-form-factor business desktop built around Intel's 14-core Core i5-14500T, 8GB of DDR5 memory and a 256GB SSD. It runs on integrated UHD Graphics 770, so it handles office work, browsing and light photo editing but not serious gaming or 3D rendering. Its main draw is the compact chassis and the 14-core CPU, which gives it more multitasking headroom than typical mini PCs with older or lower-core chips. It suits desk-bound office users and home workers who want a quiet, space-saving machine rather than a tower.

Questions and answers

Is the HP Pro Mini 400 G9 good for everyday office work?
Yes. The 14-core Core i5-14500T, DDR5 memory and SSD handle email, documents, spreadsheets and video calls smoothly. Heavy gaming or 3D rendering is not its strength.
Can I upgrade the RAM and storage?
The Pro Mini 400 G9 is a business desktop designed with serviceable internals, so memory and the M.2 SSD can typically be upgraded. Check the exact slot and module configuration before buying.
Does it come with a keyboard and mouse?
Yes. HP includes a keyboard and mouse with this configuration.
How does it compare with a full-size desktop tower?
It uses the same class of Core i5 CPU in a much smaller case. You trade expansion room for a smaller footprint, which suits most office users.

Only lightly. The integrated UHD Graphics 770 handles older or low-demand titles at low settings, but it is not a gaming machine.

Yes. It is compact, quiet in normal use and includes input devices, making it a simple fit for a home desk.
