Business Desktop

This HP ProDesk 400 small-form-factor desktop is built for office and business workloads. It ships with Windows 11 Pro and an Intel Core i5-14500 processor that reaches 5.0 GHz turbo frequency. The system includes 64GB of DDR5 4800 memory in a 32 GB x 2 configuration and a 2TB NVMe SSD. Integrated Intel UHD Graphics drive up to three displays via HDMI and DisplayPort.

Suited For And Not For

It suits professionals who need strong multi-threaded CPU performance for productivity, multitasking and video conferencing. The 14 cores and 20 threads handle heavy browser loads and business applications smoothly. Buyers who require a discrete graphics card for 3D rendering, CAD or gaming cannot add one in this chassis. Users needing more than 64GB of memory or additional internal drive bays should consider a larger platform.

Deciding Specification

The Intel Core i5-14500 delivers 14 cores and 20 threads with a 2.6 GHz base clock and 5.0 GHz max turbo. The 24 MB L3 cache helps sustain throughput across parallel workloads. This processor specification determines whether the system meets your compute requirements.

Questions about this item

Will my older USB 3.0 and HDMI monitors work with the 8 USB Type-A, 1 HDMI and 1 DisplayPort on this ProDesk 400?

Yes — the 8 USB Type-A ports are backward-compatible with USB 3.0 and 2.0 devices, and both the HDMI and full-size DisplayPort accept standard cables from existing monitors.

How can I confirm the 64 GB DDR5-4800 and 2 TB NVMe SSD are recognised after first boot?

Open Task Manager → Performance to see 64 GB DDR5 at 4800 MT/s and 2 TB NVMe capacity; Windows 11 Pro also lists both in Settings → System → Storage and About.

Does the box include a Wi-Fi antenna and display cables, or must I buy them separately?

The Wi-Fi antenna is included; display cables for HDMI or DisplayPort are not, so purchase the cable that matches your monitor.
