HP Pro 400 G9 Mini PC i3-13100T 32GB 1TB NVMe Win

This compact desktop targets home-office users and students who need responsive everyday performance in a small footprint. The Intel Core i3-13100T quad-core processor runs at 2.5GHz base with a 4.2GHz turbo frequency, supported by 32GB of DDR4 memory and a 1TB NVMe SSD. Integrated Intel UHD Graphics handles standard display output over HDMI and DisplayPort. Windows 11 Pro is pre-installed and the unit includes wired keyboard and mouse. Gigabit Ethernet and Wi-Fi 6E provide network connectivity. A 90W power supply powers the system.

Upgrade from older office desktops or basic laptops

Buyers replacing ageing tower PCs or entry-level notebooks will notice faster boot times and smoother multitasking thanks to the NVMe storage and 32GB memory configuration. The jump is worth it when current hardware struggles with multiple browser tabs, video calls or large document handling. The mini form factor frees desk space compared with traditional towers. This configuration does not suit buyers who need discrete graphics performance, expandable drive bays or user-replaceable memory slots beyond the factory specification.

Simple setup with integrated peripherals

Installation consists of connecting power, a display via HDMI or DisplayPort, and the included wired keyboard and mouse. The 90W external power adapter plugs directly into the unit. Windows 11 Pro activates on first boot. Common issues include forgetting to enable the Wi-Fi 6E antenna in BIOS for maximum wireless throughput, or overlooking the single 1TB NVMe limit when planning future storage expansion. No internal cable routing is required. The compact chassis measures 17.7 x 17.5 x 3.4 cm.

Questions about this item

What are the exact dimensions of the HP Pro 400 G9 Mini PC so I can check if it fits my desk space?

The unit measures 17.7 cm wide, 17.5 cm deep and 3.4 cm high, making it small enough to sit behind a monitor or tuck into a tight shelf.

Does the HP Pro 400 G9 Mini PC ship with a mounting bracket, and what is the common mistake when attaching it to a VESA mount?

A VESA bracket is included; the step most people miss is tightening the four M3 screws fully before snapping the PC onto the bracket, otherwise it can sag.

Is the 32 GB DDR4 memory in the HP Pro 400 G9 Mini PC soldered or socketed, and can I replace the 1 TB NVMe SSD myself later?

The 32 GB DDR4 uses two SO-DIMM slots so you can upgrade later, and the 1 TB NVMe SSD sits in a standard M.2 2280 slot for easy replacement.
