HP ProDesk 400 G3 Mini Desktop PC i5-6500T 16GB DDR4 1TB SSD Windows 10 Pro

Compact Business Desktop

The HP ProDesk 400 G3 Mini is a small-form-factor desktop computer built for office environments that need a capable workstation without a large tower. It ships new with Windows 10 Pro 64-bit, a wired keyboard and mouse combo, a Wi-Fi adapter and a power cord. The unit uses integrated Intel UHD Graphics 630 rather than a discrete card. It suits administrators who deploy standardised fleets for general productivity tasks.

16 GB DDR4 Memory

The single specification that determines fit for most buyers is the 16 GB of DDR4 system memory installed at the factory. This capacity handles typical multi-tab browsing, document editing and light multitasking without swapping to the 1 TB solid-state drive. The memory type is DDR4 only; no other generation is compatible with this platform. Buyers who need more storage or more RAM for virtual machines or heavy creative suites should look elsewhere.

Sustained Thermal Behaviour

Under continuous load the 2.50 GHz base processor can boost toward 2.80 GHz while the mini chassis relies on its internal airflow design to manage heat. The integrated GPU shares system memory and does not add a separate thermal zone. Performance remains stable for extended office workloads such as video conferencing and spreadsheet calculation. The compact form factor limits peak clocks during prolonged maximum utilisation compared with larger towers.
