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.

Questions about this item

How far can the 240 W power supply go when the i7-14700 runs at 5.4 GHz all day?

The 240 W unit caps total system draw; sustained turbo on the 20-core CPU will hit that limit before the processor reaches its thermal ceiling.

Does the small-form-factor chassis stay quiet during an all-day workload?

Fan speed ramps with CPU package power; expect audible airflow once the 18-core processor holds high frequencies for extended periods.

Which display cables do I need to use the two video outputs?

One HDMI and one DisplayPort cable are required; neither is included with the desktop.
