HP Pro 400 G9 Desktop with i7-14700

The HP Pro 400 G9 is a small-form-factor desktop built around an Intel Core i7-14700 processor. It ships with 16GB of DDR5 memory at 4800MHz and a 1TB NVMe SSD. Windows 11 Pro is pre-installed and the system includes a wired keyboard and mouse. A 240W power supply drives the platform.

Suited to office and home-office users needing

The 20-core CPU and fast DDR5 memory handle everyday productivity, video calls and light content creation smoothly. Integrated Intel UHD Graphics supports up to two displays via HDMI and DisplayPort. Buyers who need discrete graphics performance, more than 64GB of RAM or a higher-wattage power supply for expansion cards should look at other configurations.

Compact chassis fits tight desk spaces

HDMI and DisplayPort outputs connect two monitors without extra adapters. Gigabit Ethernet and Wi-Fi 6 (802.11ax) provide wired and wireless network options. The 240W internal supply powers the base specification; adding power-hungry expansion cards would require verifying headroom. Memory can be upgraded to 64GB across available slots.

Questions about this item

Which DDR5 speed does the 16GB memory run at out of the box?

The installed DDR5 modules operate at 4800MHz, matching the processor's default memory controller speed.

Can I keep using my older DisplayPort monitor with the integrated Intel UHD Graphics?

Yes, the rear DisplayPort output supports legacy displays, and the integrated graphics will drive it at its native resolution.

How can I verify the i7-14700 is reaching its 5.4GHz turbo frequency under load?

Open Task Manager's Performance tab or a tool like HWMonitor while running a heavy workload; the CPU clock should show 5.4GHz on active cores.
