Compact business mini PC

The HP ProDesk 400 G4 mini PC delivers a six-core Intel Core i5-8500T processor with a 2.1GHz base and 3.5GHz turbo frequency. Eight gigabytes of DDR4 SO-DIMM memory and a 256GB NVMe SSD provide responsive performance for office applications. Windows 10 Pro is pre-installed, and the 65W power supply keeps energy use low. Integrated Intel UHD Graphics 630 drives two DisplayPort outputs for dual-monitor setups.

Upgrade from older small-form-factor desktops

Replacing a legacy tower or an earlier mini PC with this unit adds six processing cores and NVMe storage speed in a fraction of the space. The jump is worth it when daily workloads involve multitasking across browser tabs, document suites and video calls. Builders who need more than 32GB of memory or a discrete graphics card should look elsewhere, as the platform maxes out at 32GB DDR4 and relies on integrated graphics only.

Fits tight workspaces and VESA mounts

The mini chassis slides behind a monitor or into a desk cubby, requiring only the included 65W adapter and a DisplayPort cable per screen. Gigabit Ethernet, Wi-Fi 5 and Bluetooth handle wired and wireless connectivity without extra cards. Two SO-DIMM slots allow memory expansion up to the 32GB limit, while the M.2 NVMe slot supports a larger drive if 256GB proves tight. No additional power cables or bulky coolers are needed.
