Compact Mini Desktop

The HP Pro 400 G9 is a Mini form-factor desktop powered by an Intel Core i3-13100T quad-core processor reaching 4.2GHz turbo frequency. It ships with 16GB DDR4 memory and a 4TB NVMe SSD running Windows 11 Pro. The 90W power supply supports home-office tasks and student workloads in a chassis measuring 17.7 x 17.5 x 3.4 cm.

Included Peripherals

A wired keyboard and wired mouse are bundled so the system works immediately after unboxing. Integrated Intel UHD Graphics drive external displays through HDMI and DisplayPort outputs. Gigabit Ethernet and Wi-Fi 6E (802.11ax) provide wired and wireless network connectivity without extra adapters.

Straightforward Setup

The small footprint fits on any desk and the external 90W adapter keeps cabling simple. Connect power, attach a monitor via HDMI or DisplayPort, plug in the included keyboard and mouse, then follow the Windows 11 Pro out-of-box experience. No internal assembly is required, though the compact case limits future internal expansion.

Questions about this item

Will the DDR4 memory need upgrading for heavier workloads later?

The 16GB DDR4 is soldered and not user-upgradable, so capacity is fixed for the life of the system.

What limits sustained performance first — the 90W power supply or the i3-13100T thermal ceiling?

The 90W supply caps total system draw, so the i3-13100T cannot maintain 4.2GHz turbo indefinitely under full load.

How loud and hot does the Mini chassis get when running all day?

The 17.7 x 17.5 x 3.4 cm Mini form factor relies on a small internal fan that becomes audible at continuous load; surface temperatures rise noticeably after hours of use.
