Ready-to-work business desktop

The HP ProDesk 400 G9 SFF arrives with an Intel Core i7-14700 processor, 64GB DDR5 memory and a 1TB SSD, all running Windows 11 Pro. It targets office teams and home professionals who need a compact, pre-configured system for daily productivity without assembly.

Bundled input and portable storage

A wired keyboard and mouse combo are included for immediate use, while a 64GB USB flash drive adds removable capacity for quick file transfers or backups. Dual video outputs — HDMI 1.4 and DisplayPort — support up to three independent monitors for extended desktop space.

Suits compact workspaces, not heavy graphics

The small-form-factor chassis fits tight desks and includes Wi-Fi 5 plus front USB-C at 10Gbps signalling. Buyers who need discrete graphics performance, additional internal drive bays or a larger power envelope should consider a tower-class workstation instead.

Questions about this item

Does the 64 GB DDR5 kit use standard JEDEC 4800 modules that I can swap myself?

Yes, the memory consists of two 32 GB DDR5 4800 modules installed in the two available slots, so future upgrades would require replacing one or both sticks.

Will the 20-core 14700 processor hit its thermal limit before the air cooler can keep up during long renders?

The 20-core 14700 runs at a 2.10 GHz base and can boost to 5.40 GHz, and the small-form-factor chassis relies on air cooling, so sustained heavy workloads will be constrained by the cooling capacity.

How loud does the fan get when the i7-14700 and UHD 770 graphics run flat-out all day?

The SFF case uses an air-cooling system; under continuous load the fan speed increases to manage the 20-core processor and integrated UHD 770 graphics, producing noticeable but typical office-level noise.
