Compact Business Mini PC

The HP ProDesk 400 G4 delivers a 6-core Intel Core i5-8500T processor with 16 GB of DDR4 memory and a 512 GB NVMe SSD in a tiny chassis. It arrives with Windows 10 Pro installed, ready for office productivity, education or light commercial workloads.

Connectivity And Expansion Ready

Dual DisplayPort outputs drive two monitors without adapters while Gigabit Ethernet, Wi-Fi 5 and Bluetooth handle wired and wireless networking. The 65 W power supply is integrated, keeping cable count low on a clutter-free desk.

Memory Ceiling Defines Upgrade Path

The board supports a maximum of 32 GB of DDR4 SO-DIMM memory, so the installed 16 GB can be doubled but not exceeded. Buyers who need more RAM headroom or a discrete graphics slot should look at larger form factors.

Questions about this item

Can the 16 GB DDR4 memory be expanded beyond the installed amount?

The board supports up to 32 GB of DDR4 SO-DIMM memory, so the current 16 GB can be doubled if required.

What limits sustained performance when the i5-8500T runs at its 3.5 GHz turbo for long periods?

The 65 W power supply caps total system draw, so the processor will throttle once the combined CPU, memory and SSD load reaches that envelope.

How loud and hot does the mini PC get when it is left on all day?

The compact chassis uses a small internal fan; under continuous load the exhaust air becomes noticeably warm and the fan runs at a constant audible speed.
