HP ProDesk 400 G9 SFF Business Desktop Computer, Intel CPU, 32GB RAM,

The HP ProDesk 400 G9 Small Form Factor (SFF) desktop provides a compact workstation solution for business and personal computing. Powered by an Intel Celeron G6900 dual-core processor running at 3.4 GHz with 4MB cache, it handles standard office tasks, web browsing, and administrative workflows in environments where desk space is limited.

Equipped with 32GB of DDR4 RAM (configurable up to 64GB) and support for up to 2TB PCIe M.2 SSD storage, this desktop is built to keep multiple applications open without hesitation. Visuals are powered by Intel UHD Graphics, supporting display output through standard HDMI 1.4 and DisplayPort 1.4 connections.

Connectivity is a key strength of this compact setup. It offers a USB Type-C port, multiple USB Type-A ports (including USB 2.0 options), an RJ-45 network jack, audio connections, and built-in Wi-Fi. It also arrives ready to deploy with Windows 11 Pro, TPM 2.0 hardware security, HP Wolf Security, and an included wired keyboard and mouse.

While memory capacity is generous, the system relies on an entry-level dual-core Intel Celeron processor and integrated graphics, making it unsuitable for heavy video editing or intensive rendering. Shoppers should also note the specific peripheral port layout when planning their monitor and accessory setup.
