Compact desktop for office and home

The HP ProDesk 400 G5 Mini is a small-form-factor PC built around an Intel Hexa-Core i5-9500T processor running at 2.1 GHz. It ships with 16 GB of memory, a 256 GB SSD and Windows 11 Pro pre-installed. The integrated Intel UHD Graphics 630 drives two DisplayPort outputs for dual-monitor setups.

USB Wi-Fi adapter adds wireless convenience

A USB Wi-Fi adapter is included so the system can connect to wireless networks without an internal card. The mini chassis still provides two memory slots supporting up to 64 GB total, leaving room for future RAM upgrades. Windows 11 Pro is the only software bundle mentioned.

Six-core CPU defines the performance tier

The i5-9500T delivers six cores at a base frequency of 2.1 GHz, setting the ceiling for multi-threaded workloads in this class. Buyers who need discrete graphics, higher core counts or larger factory storage should look at larger workstation configurations.

Questions about this item

Can I add more RAM later and how many slots are free?

The system has two memory slots supporting up to 64 GB total, so you can add modules if one or both slots are still empty.

What will limit performance first during a long compile or render job?

The integrated Intel UHD Graphics 630 shares system memory and has no dedicated VRAM, so graphics-heavy sustained workloads hit that ceiling first.

How loud and hot does the mini chassis get when it runs all day?

The low-profile 2.1 GHz hexa-core chip and small internal fan keep noise low, but the compact case can warm up noticeably under continuous load.
