HP ProDesk 400 G9 SFF Business Desktop

The HP ProDesk 400 G9 SFF is a compact business desktop built around a 24-core Intel Core i9-14900K processor. It ships with 32GB of DDR5-4800 memory and a 2TB PCIe NVMe SSD. Windows 11 Pro is pre-installed. Integrated Intel UHD Graphics 770 drives up to two displays via HDMI 1.4b and DisplayPort 1.4a.

Who This Suits and Who Should Look Elsewhere

This system suits offices needing high single-thread and multi-thread performance in a small chassis with dual-monitor support. Buyers who need discrete graphics acceleration, internal optical media reading, or more than 64GB of total memory capacity should consider other configurations.

180W Power Supply Limits Expansion

The 180-watt power supply constrains the PCI Express 4.0 x16 slot to low-profile cards with modest power draw. Verify that any add-in GPU or accelerator fits within this budget before purchase.
