Compact desktop for everyday office work

The HP ProDesk 400 G6 SFF runs a Core i5-9500 with six cores at 3 GHz base and 4.4 GHz turbo. Eight gigabytes of DDR4-2666 and a 128 GB NVMe drive handle web apps, documents and email. Windows 11 Pro is pre-installed. The small-form-factor chassis suits tight desks in home offices or classrooms.

Straightforward setup with limited expandability

Plug in power, a display via the onboard video ports and peripherals to start working. The 180 W internal supply leaves little headroom for discrete graphics cards or many extra drives. Only low-profile cards that fit the SFF slots and stay within the power budget can be added. Opening the case requires sliding the cover off after removing a thumb screw.

Integrated graphics and modest storage cap heavy

Intel UHD Graphics 630 drives typical business displays but cannot accelerate modern 3-D workloads or multiple high-resolution monitors. The single 128 GB NVMe volume fills quickly with large media libraries or local databases. Memory tops out at the installed 8 GB DDR4-2666 because the board has no free slots for expansion. Buyers who need more storage, more RAM or dedicated GPU performance should look at larger configurations.

Questions about this item

How can I confirm the Intel Core i5-9500 is running at its 4.4 GHz turbo frequency after setup?

Open Task Manager, select the Performance tab and watch the CPU speed reach 4.4 GHz when a demanding task runs on the 6-core processor.

What comes in the box and what must I buy separately?

The desktop, a power cord and documentation are included; a monitor, keyboard and mouse are not supplied.

Is the 128 GB NVMe SSD enough or should I choose a larger capacity?

The 128 GB PCIe NVMe TLC M.2 drive holds Windows 11 Pro and core apps; add a second internal drive or external storage for large media libraries.
