Ready for business tasks

The HP ProDesk 400 G4 is a small-form-factor desktop built around an Intel Core i7-7500 processor with four cores running at 3.4GHz base and 3.8GHz turbo. It ships with 16GB of DDR4 memory at 2400MHz and a 512GB solid-state drive, plus a DVD±R/RW optical drive. Windows 10 Pro is pre-installed, and a wired keyboard and mouse are included in the box.

Wired input and optical media included

The bundled keyboard and mouse connect via USB so the system is usable immediately without extra purchases. The DVD±R/RW drive adds the ability to read and write discs for legacy software installation or data archiving. Integrated Intel HD Graphics 630 drives the video outputs, while Gigabit Ethernet and Wi-Fi 5 provide network connectivity.

Video limited to DisplayPort and VGA

Only one DisplayPort and one VGA port are available for external displays, so multi-monitor setups beyond two screens are not supported. The 180W power supply restricts the addition of high-power expansion cards or additional drives. Maximum memory capacity is 64GB across the available slots, limiting future upgrades beyond the installed 16GB.

Questions about this item

How much DDR4 memory can the ProDesk 400 G4 take if I need to upgrade beyond the 16 GB installed?

The board supports up to 64 GB of DDR4-2400, so you can add modules until you reach that ceiling.

Will the 180 W power supply limit the i7-7500 during long compile jobs?

The 180 W unit is sized for the stock CPU and integrated graphics; sustained turbo at 3.8 GHz stays within that envelope.

How loud does the small-form-factor chassis get when the system runs all day?

Fan noise stays at a low office hum because the 65 W quad-core and integrated HD 630 graphics produce modest heat.
