HP EliteDesk 800 G9 Mini desktop PC, Core i7-12700T, 32GB DDR5, 1TB NVMe

Compact Business Desktop

The HP EliteDesk 800 G9 Mini is a new ultra-small form factor PC built for business environments where desk space is limited. It ships with Windows 11 Pro and includes a USB keyboard and mouse. The Intel Core i7-12700T processor delivers 12 cores, combining 8 performance cores with 4 efficient cores for responsive multitasking. Integrated Intel UHD Graphics 770 supports up to three 4K displays via HDMI and DisplayPort.

Sustained Workload Behaviour

The 65 W power supply and compact chassis constrain the processor to its 1.40 GHz base frequency during extended heavy loads rather than the 4.70 GHz turbo. Twelve cores and 25 MB cache maintain throughput for parallel business applications, while DDR5 memory at 32 GB reduces bottlenecks. Thermal design prioritises quiet operation over peak frequency, so single-thread bursts run faster than continuous all-core tasks.

Pre-Installation Checks

Verify that your monitors accept HDMI or DisplayPort inputs for the three-screen 4K setup. The single M.2 NVMe slot and one 2.5-inch SATA bay limit internal storage expansion to two drives. Wired networking uses a 2.5G Ethernet port, so confirm your switch or router supports that speed. The 65 W external adapter requires a free mains outlet near the mounting location.
