HP Pro 400 G9 Mini Desktop PC i3-13100T 16GB DDR4 1TB NVMe Windows 11 Pro

Compact Mini PC for Home and Office Use

The HP Pro 400 G9 Mini desktop measures 17.7 x 17.5 x 3.4 cm and weighs under three pounds. It is built for students and home-office users who need a small, quiet system for everyday tasks. The Intel Core i3-13100T processor runs at a base frequency of 2.5 GHz and can reach a turbo frequency of 4.2 GHz across its four cores. Integrated Intel UHD Graphics handles standard display output without a discrete card.

Connectivity Limits of Gigabit Ethernet and Wi-Fi 6E

Wired networking tops out at Gigabit Ethernet speeds, so large file transfers across a local network will saturate at that ceiling. Wireless uses Wi-Fi 6E (802.11ax) which requires a compatible router to reach its potential; older access points will fall back to slower standards. The 90 W power supply is matched to the low-power processor and integrated graphics, leaving no headroom for power-hungry add-in cards. Video output relies on the integrated graphics through HDMI and DisplayPort only.

Straightforward Setup With Proprietary Constraints

The package includes a wired keyboard and mouse, so the system is ready to run once a monitor is connected. Windows 11 Pro is pre-installed and activated. The Mini form factor uses proprietary internal layouts, which makes upgrading the 16 GB DDR4 memory or the 1 TB NVMe SSD more difficult than on a standard tower. Opening the chassis may require specific tools and care to avoid damaging the compact cooling assembly.
