Compact desktop for everyday tasks

The Acer Aspire XC-840-UB11 is a small-form-factor desktop built around an Intel Celeron N4505 processor with integrated Intel UHD Graphics. It ships with 16 GB of DDR4 memory and a 512 GB NVMe solid-state drive. Windows 11 Pro is pre-installed, making it ready for office applications, web browsing and media playback straight out of the box.

Fits tight spaces and adds wireless

The chassis measures 12.99 by 3.94 by 11.61 inches and weighs 9.26 lb, so it can sit on a desk shelf or behind a monitor without dominating the workspace. A 65-watt power supply is integrated, removing the need for an external brick. Built-in Wi-Fi 6 and Bluetooth 5.3 provide cable-free networking and peripheral connections, freeing USB ports for other devices.

Wired input kit included

A wired keyboard and wired mouse are bundled, so the system is usable immediately without buying separate input devices. The board supports up to 32 GB of DDR4 and up to 1 TB of NVMe storage for future expansion. Buyers who want more storage bays, discrete graphics or a larger power envelope will need a different platform.

Questions about this item

How far can the 16 GB DDR4 memory be expanded before the system hits its ceiling?

The motherboard supports up to 32 GB of DDR4 so you can add another 16 GB module if you need more headroom.

What does the 65 watt power supply mean for heat and fan noise during an all day workload?

A 65 watt brick keeps thermal output modest; the small chassis runs warm but the fan stays at a low, steady speed.

Which display connector do I need on my monitor to use the integrated Intel UHD Graphics?

The rear panel provides HDMI and VGA ports so any monitor with either input will work without an adapter.
