Ready-to-use mini desktop

The HP ProDesk 400 G3 Tiny is a compact desktop computer built for everyday office tasks. It ships with Windows 10 Pro 64-bit installed and includes 16GB of system memory plus a 512GB solid-state drive. The Intel Core i5-6400T processor runs at 2.20 GHz and handles standard productivity workloads without needing a full-size tower.

Ideal for fixed workstations, not for mobile users

This unit suits buyers who need a small, quiet PC that stays on a desk and connects to their own display. It is not suited to anyone who requires an integrated screen, battery power or a larger chassis that accepts full-height expansion cards.

Video output limited to DisplayPort and VGA

The system provides one DisplayPort and one VGA connector driven by Intel UHD Graphics 630. Buyers whose monitors only accept HDMI, DVI or USB-C video will need an adapter or a different machine.

Questions about this item

Can the 512GB SSD be swapped for a larger drive later?

The 512GB SSD is removable, so you can replace it with a higher-capacity unit when storage needs grow.

What limits performance first during long workloads on the Core i5-6400T?

The 2.20 GHz base clock and integrated Intel UHD Graphics 630 share the tiny chassis thermal budget, so sustained CPU or GPU load throttles clocks first.

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

The small fan spins up under continuous load, producing noticeable airflow noise while exhausting heat through the compact case vents.
