HP ProDesk 400 G4 SFF i5-7500 8GB 256GB SSD Windows 10 Pro desktop PC

Small-form-factor desktop for office work

The HP ProDesk 400 G4 SFF is a compact business PC built around an Intel Core i5-7500 processor running at 3.4 GHz up to 3.8 GHz. It ships with 8 GB of DDR4 memory, a 256 GB SSD and Windows 10 Pro pre-installed. The small chassis suits home offices, classrooms or reception desks where space is limited.

180 W power supply and front-access ports

An internal 180 W supply powers the system without an external brick. The case provides eight USB ports in total and two video outputs, letting you connect multiple peripherals and dual displays without adapters. An included USB Wi-Fi adapter adds wireless connectivity, while a dust filter option helps reduce particulate build-up in busy environments.

Check display inputs and expansion room

Verify that your monitors accept the two video connections available on this unit before ordering. The slim form factor restricts internal card length and height, so discrete graphics upgrades may not fit. The 180 W supply also limits the power headroom for additional components. Buyers who want more storage bays or a full-size graphics card should consider a larger chassis.
