HP ProDesk 400 G9 SFF business desktop

This small-form-factor desktop is built for office and business use. It ships with Windows 11 Pro and includes a wired keyboard, mouse, and a 64 GB USB flash drive. The air-cooled chassis measures 10.6 x 3.7 x 12.1 in and weighs 9.25 lbs.

Suits users needing multi-monitor productivity

The integrated Intel UHD Graphics 770 drives up to three independent displays via rear HDMI 1.4 and DisplayPort. Buyers who require discrete graphics performance for rendering or gaming should consider other systems. The 32 GB DDR5 4800 memory (16 GB x 2) leaves two slots free for expansion up to 64 GB.

2 TB NVMe SSD provides ample space

The 20-core Intel Core i7-14700 runs at 2.10 GHz base and 5.40 GHz turbo with 33 MB L3 cache, handling heavy multitasking and background services. Storage headroom ends at the single M.2 slot limit; users needing more capacity must replace the drive.

Questions about this item

What monitor cables and ports do I need to run two 4K displays on the Intel UHD Graphics 770?

Use the rear HDMI 1.4 and DisplayPort outputs. Both support 4K resolution, letting you drive two monitors without an adapter.

Will my existing USB 3.0 Type-A peripherals work with the front 10 Gbps Type-A ports?

Yes. The three front SuperSpeed USB Type-A ports run at 10 Gbps and are backward compatible with USB 3.0 and 2.0 devices.

How can I verify the DDR5 memory is running at 4800 MT/s after first boot?

Open Task Manager, select the Performance tab, click Memory, and confirm the speed reads 4800 MT/s.
