Compact Business Mini PC

The HP Elite Mini 800 G9 delivers an Intel Core i5-12500T processor with 32GB DDR5 memory and a 512GB NVMe SSD in a small black chassis. It ships with Windows 11 Pro and Intel UHD Graphics 770 for everyday office workloads. The 12th generation CPU provides 18MB L3 cache for responsive multitasking. This refurbished unit suits professionals needing capable performance in minimal desk space.

Versatile Connectivity Layout

One USB-C 3.2 Gen 2 port and five USB-A ports handle peripherals and external drives. Video output uses one HDMI 2.1 and two DisplayPort 1.4a connectors for up to three displays. A single RJ-45 jack provides wired networking alongside a 3.5mm audio jack. The port selection covers modern docks, legacy accessories and multi-monitor setups without adapters.

Integrated Graphics Constraints

Intel UHD Graphics 770 handles general productivity, video playback and multi-monitor desktop spanning. It is not suited for 3D rendering, CAD visualisation or modern gaming workloads. Buyers needing discrete GPU performance for creative or engineering applications should consider a workstation tower instead. The mini form factor prevents internal graphics upgrades.

Questions about this item

What video standard do the HDMI 2.1 and DisplayPort 1.4 ports support on this Elite Mini 800 G9?

The HDMI 2.1 and two DisplayPort 1.4 ports are driven by the integrated Intel UHD Graphics 770, which sets the practical resolution and refresh-rate ceiling for connected displays.

What physical space and mounting options does the HP Elite Mini 800 G9 require?

The mini PC uses a compact black chassis designed for VESA mounting behind a monitor or placement on a desk, with all ports — HDMI 2.1, two DisplayPort 1.4, RJ-45, USB-C 3.2 Gen 2, five USB-A and a 3.5 mm audio jack — accessible on the rear and front faces.

How is the HP Elite Mini 800 G9 set up, and which step is often missed?

Connect power, attach a display to HDMI 2.1 or DisplayPort 1.4, plug in the RJ-45 cable, then complete the Windows 11 Pro first-run setup; the step users frequently skip is checking for and installing the latest HP driver pack so the Intel UHD Graphics 770 and all USB 3.2 Gen 2 ports operate correctly.
