HP J1-400G6SA10 ProDesk 400 G6-SFF Business Desktop i5-9600 16GB DDR4 512GB SSD

ProDesk 400 G6-SFF refurbished business desktop

This refurbished HP ProDesk 400 G6-SFF is a slim-form-factor business desktop built around an Intel Core i5-9600 six-core processor running at 3.10 GHz. It ships with 16 GB DDR4 memory and a 512 GB 2.5-inch SSD, plus Windows 11 Pro 64-bit pre-installed. The compact chassis suits office desks where space is limited.

Intel Core i5-9600 six-core processor

The single specification that determines fit is the Intel Core i5-9600, a 9 MB L3 cache six-core CPU operating at 3.10 GHz. It provides 64-bit processing for typical office workloads, web apps and light multitasking. Buyers who need more cores, higher clock speeds or a discrete graphics option should look elsewhere.

Integrated Intel UHD Graphics 630 under load

Graphics are handled by the integrated Intel UHD Graphics 630, which shares system memory and has no dedicated video RAM. Under sustained load the GPU will throttle to stay within the small-form-factor thermal envelope, so extended 3D rendering or multi-monitor heavy use will run slower than a brief burst. The 3.70 by 10.60 by 11.70 inch case limits airflow compared with larger towers.
