Aspire XC-840 compact desktop

The Acer Aspire XC-840-UB11 is a tower-format desktop PC built around an Intel Celeron N4505 dual-core processor. It ships with 32GB of DDR4 memory running at 2933 MT/s and a combined 2TB of storage split between an internal 1TB SSD and a bundled 1TB docking station. Windows 11 Pro is pre-installed alongside a USB keyboard and mouse.

Suited for everyday office and home tasks

This system handles web browsing, document creation and light multitasking without difficulty. The integrated Intel UHD Graphics drives HD video playback and 5.1-channel audio through HDMI. Buyers who need more storage than the supplied 2TB or who require discrete graphics for heavier creative workloads should consider a different configuration.

Sustained low-power operation

The Celeron N4505 is designed for stable low-power performance rather than short bursts of high speed. Under continuous load the processor maintains its base behaviour without aggressive throttling, and the compact chassis relies on passive airflow suited to its modest thermal envelope. Wi-Fi 6 (802.11ax) connectivity remains consistent during extended sessions.

Questions about this item

What display cable do I need to use the Intel UHD Graphics on this XC-840-UB11?

The desktop provides an HDMI output for the Intel UHD Graphics, so connect your monitor with an HDMI cable to get video and 5.1-channel surround sound.

Will my existing USB 2.0 keyboard and mouse work with the four rear and two front USB ports on this tower?

Yes, the USB ports on the XC-840-UB11 are backward compatible, so your current USB 2.0 peripherals will function normally alongside the bundled USB keyboard and mouse.

How can I confirm the 32 GB DDR4 2933 memory is recognised after I power on the system?

Open Task Manager in Windows 11 Pro, select the Performance tab, and verify that 32 GB of DDR4 memory running at 2933 MT/s is shown.
