Compact desktop for everyday workloads

The HP Pro 400 G9 is a small-form-factor desktop built around an Intel Core i5-14500 processor with eight cores and a turbo frequency up to 5GHz. It ships with 8GB of DDR5 memory at 4800MHz and a 1TB NVMe solid-state drive. Windows 11 Pro is pre-installed, and the unit includes a wired keyboard and mouse.

Suited for office and home study.

This system fits students, home-office users and small-business staff who need responsive performance for web apps, document editing and video calls. The 8GB memory ceiling limits simultaneous heavy applications or large dataset work. Buyers who want more memory headroom or discrete graphics for rendering should look at something else.

SFF chassis with dual-display output and wired

The case provides HDMI and DisplayPort connectors to drive two monitors from integrated Intel UHD Graphics. Gigabit Ethernet and Wi-Fi 6 (802.11ax) handle wired and wireless connectivity. A 240W internal power supply powers the platform, and the motherboard supports up to 64GB of DDR5 for future upgrades.

Questions about this item

What display cables or adapters do I need to connect two monitors to the HDMI and DisplayPort outputs?

The desktop provides one HDMI port and one DisplayPort output, so you can attach two monitors directly with matching cables or adapters for each port.

Will the DDR5 memory run at its rated 4800 MHz speed with the installed Core i5-14500 processor?

Yes, the i5-14500 memory controller supports DDR5 at 4800 MHz, so the 8 GB module will operate at that speed without manual adjustment.

How can I confirm the 1 TB NVMe solid-state drive is recognised and set as the boot device after first power-on?

Open Windows Settings, go to System > Storage and verify the 1 TB drive appears; then restart and enter UEFI to confirm it is listed first in the boot order.
