Compact Mini PC for everyday work

The HP Pro 400 G9 is a Mini desktop measuring 17.7 x 17.5 x 3.4 cm and weighing under 3 pounds. It runs Windows 11 Pro on an Intel Core i3-13100T processor with a 2.5 GHz base frequency and 4.2 GHz turbo frequency across four cores. The system includes 8GB DDR4 memory and a 1TB NVMe SSD for fast boot and data access. Integrated Intel UHD Graphics drive video output through HDMI and DisplayPort connections.

Suited for light multitasking, not heavy workloads

This desktop fits home offices, student desks and general business tasks such as document editing, web browsing and video calls. Gigabit Ethernet and Wi-Fi 6E provide wired and wireless network options. A wired keyboard and mouse are included in the box. Buyers who need discrete graphics performance, larger memory capacity or multiple high-speed storage bays should consider a different form factor.

90 W power supply limits expansion

The unit ships with a 90 W internal power supply that defines the total power budget for the processor, memory, storage and any peripherals connected through the available ports. This constraint determines whether additional components can be added without exceeding the system’s power delivery capability. Verify the power requirements of any planned upgrades against this 90 W limit before purchase.

Questions about this item

Will the 90W power supply sustain the i3-13100T at its 4.2GHz turbo under continuous load?

The 90W unit powers the i3-13100T, 8GB DDR4, 1TB NVMe SSD and integrated graphics; the processor runs at 2.5GHz base and can reach 4.2GHz turbo within that envelope.

How loud or hot does the Mini chassis get when the system runs all day at 4.2GHz?

The 17.7 x 17.5 x 3.4 cm Mini form factor uses a 90W supply; fan noise and surface temperature rise with sustained turbo but remain within normal desktop limits for this class.

Which display cables or adapters must I already own to connect a monitor?

The desktop provides HDMI and DisplayPort outputs; you need a matching cable for your monitor — no video cable is included in the box.
