HP Pro 400 G9 Desktop PC

This HP Pro 400 G9 small-form-factor desktop ships new with Windows 11 Pro pre-installed. It targets home-office workers, students and small-business users who need a compact, ready-to-run system for everyday productivity and multitasking. A wired keyboard and mouse are included in the box.

20-core Intel Core i7-14700 processor

The CPU delivers 20 cores with a 1.5 GHz base frequency and a 5.4 GHz turbo frequency, supported by 33 MB of SmartCache. This specification determines whether the system can handle heavier multithreaded workloads such as content creation or data analysis alongside standard office tasks.

32 GB DDR5-4800 memory and 4 TB NVMe SSD

Memory runs at 4800 MHz and the board supports up to 64 GB total, so future upgrades are possible without replacing modules. The 4 TB NVMe drive provides high-capacity, low-latency storage for large project files and applications. The 240 W power supply and integrated Intel UHD Graphics limit discrete GPU upgrades, while HDMI and DisplayPort outputs drive up to two external displays. Gigabit Ethernet and Wi-Fi 6 (802.11ax) handle wired and wireless networking.

Questions about this item

How does the 5.4GHz turbo frequency behave when the i7-14700 is inside this SFF chassis with a 240W power supply?

The processor can reach 5.4GHz on one or two cores when thermal headroom allows; sustained all-core speeds will be lower because the 240W supply and compact case limit heat dissipation.

What display outputs does the integrated Intel UHD Graphics provide, and how many monitors can they drive?

The rear panel includes HDMI and DisplayPort; the integrated graphics can drive two displays simultaneously from these native ports.

What physical space and power connections does the 4TB NVMe SSD require inside the Pro 400 G9?

The drive uses an M.2 2280 slot on the motherboard and draws power directly from the slot — no extra cables or 2.5-inch bay space are needed.
