Acer Aspire XC-840-UB11 desktop PC, Celeron N4505, 16 GB DDR4, 512 GB NVMe, Windows 11 Pro

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.
