Compact Business Desktop for Office Work

The HP ProDesk 400 G5 SFF is a small form factor desktop built for everyday business tasks. It runs an Intel Core i3-8100 processor at 3.6GHz with Intel UHD Graphics 630. The system includes 16GB of DDR4 memory at 2666 speed and a 512GB SSD. Windows 11 Pro comes pre-installed along with a keyboard, mouse and USB Wi-Fi adapter.

Suited for Document and Web Workloads

This configuration handles word processing, spreadsheets, email, web browsing and video conferencing smoothly. It also supports programming, development and basic photo or video editing. Buyers who need discrete graphics for 3D rendering or heavy creative suites should look elsewhere. The 180W power supply and compact chassis limit expansion card options.

Steady Output in a Small Chassis

Air cooling manages heat during extended office sessions without throttling the 3.6GHz processor. Integrated graphics share system memory, so sustained GPU compute tasks remain modest. The DDR4 memory and SSD keep multi-tasking responsive over long periods. Thermal headroom is sized for typical business duty cycles rather than continuous maximum load.

Questions about this item

Does the i3-8100 3.6GHz processor need a separate graphics card or does the integrated Intel UHD Graphics 630 handle the display?

The Intel UHD Graphics 630 built into the i3-8100 drives the video outputs directly, so no discrete graphics card is required for normal business use.

Will my existing DDR4 2666 memory modules work if I want to expand beyond the installed 16GB?

The system uses DDR4 2666 memory; matching modules of the same speed and type will work together with the factory-installed 16GB.

How can I confirm the 512GB SSD and Windows 11 Pro are recognised after first boot?

Open Settings, go to System then Storage to see the 512GB drive, and check About to verify Windows 11 Pro is active.
