Compact SFF desktop for business and home

The HP ProDesk 400 G6 SFF is a small form factor desktop built around an Intel Core i7-9700 eight-core processor. With 32GB DDR4 memory and a 512GB NVMe SSD it delivers responsive performance for office applications, multitasking and everyday productivity. Windows 11 Pro is pre-installed and TPM 2.0 security is included for enterprise-grade data protection. Built-in WiFi removes the need for a separate wireless adapter.

Connectivity and expansion inside the chassis

Dual DisplayPort outputs support two monitors for extended workspace without an additional graphics card. Multiple USB 3.1 and USB 2.0 ports provide connections for printers, external storage and peripherals. Fast Ethernet handles wired network links while integrated WiFi covers wireless access. The compact chassis saves desk space and uses air cooling, so no liquid-cooling loop or external radiator is required.

Sustained workload behaviour

The eight-core processor operates at a 3.00GHz base frequency and can reach 4.70GHz under load, allowing consistent throughput during extended multitasking sessions. The 12MB L3 cache helps maintain performance when several applications run simultaneously. Intel UHD Graphics 630 handles standard display output and video playback without a discrete GPU. Air cooling and an energy-efficient design keep power draw modest during prolonged operation.
