Compact desktop for everyday tasks

The Acer Aspire XC-840-UB11 is a small-form-factor Windows 11 Pro PC built around an Intel Celeron N4505 processor with integrated Intel UHD Graphics. It ships with 8 GB of DDR4 memory and a 512 GB NVMe solid-state drive, plus a wired keyboard and mouse. The chassis measures 12.99 by 3.94 by 11.61 inches and weighs 9.26 lb, making it suited to tight desk spaces or basic office deployments.

Sustained-load behaviour

Under continuous workloads the 65-watt power supply feeds the low-power Celeron N4505 and its integrated graphics, so thermal headroom is modest but adequate for web browsing, document editing and video playback. The 8 GB DDR4 configuration handles typical multitasking without heavy paging, while the NVMe drive keeps boot and application launches responsive. Wi-Fi 6 and Bluetooth 5.3 maintain stable wireless links during extended sessions.

Installation notes and common issues

The system arrives with the original seal opened only for the advertised memory and storage configuration, so no further assembly is required beyond connecting power, display and peripherals. Memory can be expanded up to 32 GB using DDR4 modules, and the M.2 slot supports up to 1 TB NVMe storage if more capacity is needed. Buyers who need discrete graphics performance or greater CPU throughput should consider a different platform.

Questions about this item

How much power does the 65 watt supply draw when the Intel Celeron N4505 runs all day?

The 65 watt power supply is rated for the Intel Celeron N4505 and Intel UHD Graphics, so typical all-day draw stays well within that limit.

Does the DDR4 memory slot need a matching stick already installed for the 8 GB to work?

The 8 GB DDR4 module ships installed, so no extra memory is required for the system to operate.

Can the Intel UHD Graphics drive a legacy VGA monitor through the existing ports?

The desktop includes modern video outputs for current displays; older VGA screens would need an active adapter not supplied with the unit.
