Compact SFF desktop for office tasks

The HP ProDesk 400 G6 is a Small Form Factor desktop built around an Intel Core i5-9500 processor running at 3.0 GHz. It ships with 16GB of DDR4 memory and a 256GB Solid State Drive. Windows 10 Pro comes pre-installed, making it ready for typical business applications and general productivity work.

Sustained workload behaviour

The 3.0 GHz base clock and six-core design handle continuous multi-threaded loads such as large spreadsheets or background database tasks without thermal throttling in the SFF chassis. The 256GB SSD maintains consistent read and write speeds during prolonged file transfers. Sixteen gigabytes of DDR4 keeps memory pressure low when several office programs run together.

Compatibility checks before ordering

Verify that your display uses either DisplayPort 1.2 or VGA, as no other video outputs are present. Plan for four USB 2.0 and four USB 3.1 ports when connecting peripherals. The system includes a single RJ-45 network jack and a headphone/microphone combo jack. No optical drive is fitted, so external media access requires a separate USB device.

Questions about this item

How quiet is the fan when the i5-9500 runs at 3.0 GHz all day in the 400 G6 SFF?

The small-form-factor chassis uses a single system fan that spins up only under sustained load; at idle it is barely audible in a typical office.

Which display cable do I need to connect a monitor to the DisplayPort 1.2 or VGA port?

You must supply your own DisplayPort 1.2 or VGA cable; no video cable is included in the box.

Can I keep using my USB 2.0 keyboard and mouse alongside the four USB 3.1 ports?

Yes — four USB 2.0 ports are provided specifically for legacy peripherals, while the four USB 3.1 ports handle faster devices.
