HP ProDesk 400 G4 SFF desktop

This HP ProDesk 400 G4 small-form-factor desktop is built for office and home-office users who need a compact Windows 10 Pro machine. It runs on an Intel Core i5-6100 processor at 3.70 GHz with 16GB DDR4 memory and a 256GB SSD. Integrated Intel HD Graphics 530 handles everyday display tasks without a discrete card.

Air cooling with 180W power supply

The system uses air cooling driven by an internal 180W power supply to manage thermals during typical productivity workloads. Acoustic output stays low enough for quiet desk environments while the chassis maintains stable temperatures. Power draw scales with the CPU and integrated graphics under normal office use.

New keyboard mouse USB Wi-Fi adapter included

The package adds a new keyboard and mouse so the PC is ready to operate immediately. A USB Wi-Fi adapter provides wireless connectivity without occupying internal expansion slots. Windows 10 Pro is pre-installed and activated for business features such as BitLocker and remote desktop.

Questions about this item

How do I install the 16GB DDR4 memory in the SFF chassis, and which slot do people often miss?

The small-form-factor board has two DDR4 slots; the second slot sits under the drive cage and is easily overlooked, so remove the cage first, seat both modules until the clips click, then refit the cage before closing the case.

What maintenance or replacement will the 180W power supply need later?

Electrolytic capacitors inside the 180W unit age with heat cycles; plan to replace the PSU after roughly five years or if the system becomes unstable under load.

What limit appears first when the Core i5-6100 runs at 3.70 GHz for long periods?

The 180W power budget and the compact air cooler restrict sustained turbo, so the CPU throttles to its base frequency once the thermal headroom is exhausted.
