Ready-to-Work Business SFF PC

This HP ProDesk 400 G9 arrives new with Windows 11 Pro, a wired keyboard, mouse and a 64 GB flash drive. The Intel Core i7-14700 20-core processor reaches 5.40 GHz turbo alongside 16 GB of DDR5 4800 memory and a 512 GB SSD. Intel UHD Graphics 770 drives two 4K displays via HDMI 1.4 and DisplayPort.

Suits office multitasking, not GPU workloads

The 20-core CPU and dual 4K video outputs handle spreadsheets, code and video calls with ease. Buyers who need discrete graphics performance, more than two native display ports or internal bays for additional 3.5-inch drives should consider a tower workstation instead.

16 GB DDR5 4800 in two 8 GB modules

The system ships with 8 GB x 2 DDR5 4800 installed, leaving two DIMM slots open for expansion up to the platform maximum. Confirm your memory requirements before ordering because the fitted capacity cannot be changed after purchase.

Questions about this item

Should I pick the 16 GB DDR5 4800 configuration or add more memory later?

The system ships with 16 GB as two 8 GB DDR5 4800 modules and supports up to 64 GB total, so you can start with the included memory and add two more modules when workloads demand it.

What does the 5.4 GHz turbo frequency deliver in everyday work?

The Intel Core i7-14700 can boost to 5.4 GHz on up to 20 cores and 28 threads, giving short bursts of high single-thread speed for snappy app launches and heavy spreadsheet recalculations.

Which video outputs does the HDMI 1.4 and DisplayPort combination actually drive?

Rear HDMI 1.4 and DisplayPort connectors support up to three independent 4K displays, letting you span spreadsheets, code editors or financial charts across multiple screens.
