HP Pro 400 G9 Desktop

The HP Pro 400 G9 is a small-form-factor desktop built for office and home users who need reliable everyday performance. It ships with an Intel Core i5-14500 processor, 32GB of DDR5 memory, and a 1TB NVMe SSD. Windows 11 Pro comes pre-installed alongside a wired keyboard and mouse. No monitor is included in the box.

Sustained workload behaviour

The 8-core processor runs at a 2.6GHz base frequency and can reach a 5GHz turbo frequency with 24MB of SmartCache. The 240W power supply delivers stable energy for continuous multitasking and productivity applications. Integrated Intel UHD Graphics handles standard display output across HDMI and DisplayPort connections. Memory operates at 4800MHz DDR5 with support for up to 64GB total capacity.

Deciding specification

The 240W power supply capacity determines which internal upgrades are possible for this chassis. Buyers who need a discrete graphics card or multiple high-power storage drives should verify the power budget before purchase. The small form factor also limits physical space for full-height expansion cards. Gigabit Ethernet and Wi-Fi 6 (802.11ax) provide wired and wireless network connectivity.

Questions about this item

How loud does the 240W power supply fan get when the Core i5-14500 runs at 5GHz all day?

The small-form-factor chassis uses a single system fan that ramps up under sustained turbo loads; expect audible airflow but no extreme whine in a typical office.

Does the wired keyboard and mouse connect via USB-A or PS/2 on this Pro 400 G9?

Both peripherals use standard USB-A connectors, so they plug directly into the front or rear ports without adapters.

Can the integrated Intel UHD Graphics drive my older 1080p monitor over VGA?

The rear panel provides HDMI and DisplayPort only; a VGA monitor requires an active DisplayPort-to-VGA adapter.
