HP Pro 400 G9 desktop

This HP Pro 400 G9 desktop is a small-form-factor PC built for everyday office work and study. It ships with Windows 11 Pro, a wired keyboard and a wired mouse. The 240W power supply runs the integrated Intel UHD Graphics and supports up to two displays via HDMI and DisplayPort. No monitor is included in the box.

20-core Intel Core i7-14700

The processor has 20 cores and a 33MB SmartCache, reaching a 5.4GHz turbo frequency from a 1.5GHz base. That core count is the single figure that determines whether the system can handle heavy multitasking and threaded workloads. Integrated graphics handle video output without a discrete card. The platform supports DDR5 memory running at 4800MHz.

8GB DDR5 and 2TB NVMe SSD

The board holds 8GB of DDR5 today and accepts up to 64GB total, so memory can be added later without replacing modules. The 2TB NVMe SSD provides the primary storage volume. Gigabit Ethernet and Wi-Fi 6 (802.11ax) give wired and wireless network connectivity. The small chassis limits internal expansion to the provided slots and bays.

Questions about this item

How does the 5.4GHz turbo frequency translate to everyday workloads on this i7-14700?

The 20-core processor reaches 5.4GHz on demand, so heavy spreadsheet recalculations and video-encoding bursts finish quickly while lighter tasks run at lower speeds to keep power draw and heat in check.

What display connections does the integrated Intel UHD Graphics provide and what limits apply?

HDMI and DisplayPort outputs support up to two monitors simultaneously; resolution and refresh rate are bounded by the integrated graphics capability and the chosen cables.

What physical space and power does the small-form-factor chassis require for installation?

The SFF case fits on a desk or shelf with a standard 240W internal supply; it ships with a wired keyboard and mouse, and no monitor is included.
