Big Performance. Tiny Package. Zero Compromises.
Meet the HP Pro Mini 400 G9—the desktop that proves you don't need a tower to get tower-level performance. At just over 3 pounds, this mini pc transforms any space into a productive workspace without the bulk, noise, or heat of traditional desktops.
See More. Do More. Three Screens at Once. Why limit yourself to one screen when you can have three? Connect up to three 4K displays and experience a workspace that adapts to you. Spreadsheet on the left, video conference in the center, research on the right. Or code on one screen, documentation on another, and testing on the third. With dual DisplayPort 1.4 and HDMI 2.1, you get crystal-clear 4K resolution across all displays—no adapters, no compromises.
Designed for Real Workspaces. Traditional desktop towers are loud, hot, and take up valuable desk space. The Pro Mini 400 G9 operates at under 30dB (quieter than a whisper), stays cool without noisy fans, and fits behind a monitor or in a desk drawer. Its compact 6.97" x 6.89" footprint leaves room for what matters—your work, your coffee, your style.
