HP ProDesk 400 G9 SFF i9-14900K 32GB DDR5 1TB NVMe Windows 11 Pro

Compact SFF business desktop

The HP ProDesk 400 G9 SFF delivers a 24-core Intel Core i9-14900K processor with 32 GB of DDR5 4800 memory and a 1 TB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed on a platform designed for commercial deployment. The small form factor chassis fits constrained workspaces while supporting dual-monitor output through HDMI 1.4b and DisplayPort 1.4a.

Thermals and 180 W power envelope

A 180 W internal supply feeds the processor, integrated Intel UHD Graphics 770, memory and storage within the compact enclosure. Intel UHD Graphics 770 operates without a discrete card, reducing total heat load and acoustic output during typical office workloads. Gigabit Ethernet, WiFi 6E and Bluetooth 5.3 connectivity are integrated on the motherboard, avoiding additional expansion cards that would increase power draw. The single PCI Express 4.0 x16 slot remains available for future upgrades if thermal headroom allows.

Included keyboard, mouse and expansion room

A USB keyboard and mouse ship in the box alongside the power cable, so the system is ready for immediate setup. Front-facing ports include three USB-A 3.2 and one USB-C 3.2 for quick peripheral access. Rear I/O adds two USB-A 2.0, three USB-A 3.2, audio in/out and RJ-45. One 3.5-inch hard-drive bay and a PCI Express 3.0 x1 slot provide internal expansion without changing the external footprint.
