HP ProDesk 400 G6 SFF i5-9500 8 GB 128 GB NVMe Win 11 Pro desktop PC

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.
