HP Pro 400 G9 SFF desktop PC Intel Core i5-14500 16GB DDR5 512GB

Compact business desktop

The HP Pro 400 G9 small-form-factor system pairs a 14-core Intel Core i5-14500 processor with 16 GB of DDR5 memory and a 512 GB solid-state drive. Windows 11 Pro, Wi-Fi 6 and Bluetooth are included alongside a wired keyboard and mouse. It targets offices that need a space-efficient workstation for everyday productivity tasks.

Upgrade path from older SFF units

The chassis accepts up to 64 GB of DDR5 and a 2 TB NVMe drive, so memory and storage can grow with workload demands. Integrated Intel UHD Graphics handles standard business displays without a discrete card. Buyers who require dedicated GPU performance or multiple high-wattage add-in cards should look elsewhere.

Sustained thermal behaviour

The slim 10.6 by 3.7 by 12.1 inch enclosure weighing 9.25 lb relies on a compact internal airflow design. Under continuous multi-threaded loads the processor will maintain base frequencies within its thermal envelope rather than sustaining peak turbo indefinitely. Fan noise remains typical for a commercial SFF platform during extended operation.
