HP Pro 400 G9 Desktop PC

This HP Pro 400 G9 desktop PC ships new with an Intel Core i7-14700 processor that reaches 5.4GHz turbo frequency across 20 cores and 33MB SmartCache. It includes 8GB DDR5 memory at 4800MHz and a 512GB NVMe SSD. Windows 11 Pro is pre-installed. The small-form-factor chassis uses a 240W power supply and comes with a wired keyboard and mouse. No monitor is included. Integrated Intel UHD Graphics drives the video outputs.

Build integration

The system provides HDMI and DisplayPort connections supporting up to two displays. Gigabit Ethernet and Wi-Fi 6 (802.11ax) handle network connectivity. Memory can be expanded to 64GB DDR5. The 240W power supply and compact chassis limit the addition of discrete graphics cards or high-wattage components. Buyers who want more storage or a dedicated GPU should verify physical and electrical constraints before purchase.

Sustained operation

The 18-core processor with a 1.5GHz base frequency is designed for multi-threaded workloads across productivity applications. Integrated graphics share system memory and thermal budget with the CPU. Under continuous heavy load the 240W power supply and small-form-factor cooling define the performance envelope. The configuration suits office tasks, video conferencing and light content creation rather than extended compute-intensive rendering.
