Compact business desktop

The HP Pro 400 G9 is a small-form-factor desktop built around an Intel Core i7-14700 processor with 20 cores and a 5.4GHz turbo frequency. It ships with 32GB of DDR5 memory at 4800MHz and a 1TB NVMe SSD. Windows 11 Pro is pre-installed, and integrated Intel UHD Graphics drive video output through HDMI and DisplayPort for up to two displays. A wired keyboard and mouse are included.

Step up from entry systems

This configuration replaces basic office PCs that rely on lower core counts, slower memory or hard-drive storage. The 18 performance and efficient cores combined with DDR5 bandwidth make the jump worthwhile when workloads include heavy multitasking, large spreadsheets or simultaneous video conferencing. Buyers who need discrete graphics, more than 64GB of RAM or a higher-wattage power supply should look elsewhere.

Build-ready small form factor

The 240W internal supply powers the CPU, memory and SSD without extra cables. Gigabit Ethernet and Wi-Fi 6 (802.11ax) handle wired and wireless networking. Two video ports support dual-monitor setups, freeing desk space in home offices or education environments. The chassis accepts up to 64GB of DDR5 if future expansion is required.

Questions about this item

What size power supply does the Pro 400 G9 SFF chassis accept?

The unit ships with a 240 W internal power supply designed for the Small Form Factor case; verify the wattage and physical dimensions before swapping to a higher-output unit.

Which screws or latches secure the side panel for internal access?

The SFF chassis uses a tool-less release latch on the rear edge; slide the latch, then lift the panel off — forcing the panel without releasing the latch is the step most people get wrong.

How much DDR5 memory can the board support in total?

The motherboard supports up to 64 GB of DDR5-4800 across two slots, so the factory 32 GB leaves one slot free for a single 32 GB module upgrade.
