Compact desktop for home and office

The HP Pro 400 G9 is a small-form-factor PC built around an Intel Core i5-14500 with eight cores and a 5GHz turbo frequency. It ships with 16GB of DDR5 memory at 4800MHz and a 4TB NVMe SSD. Windows 11 Pro is pre-installed and a wired keyboard and mouse are included.

Interface limits for display and network

Video output relies on integrated Intel UHD Graphics driving HDMI and DisplayPort connections for up to two monitors. The wired network link is Gigabit Ethernet and wireless uses Wi-Fi 6 (802.11ax). The internal power supply is rated at 240W, which constrains the total power available for any added components.

Memory ceiling decides upgrade path

The motherboard supports a maximum of 64GB of DDR5 across its slots, so the installed 16GB leaves room for expansion but cannot be exceeded. Buyers who need more than 64GB of system memory must choose a different platform.
