Acer Aspire XC-840-UB11 desktop PC Celeron N4505 16GB DDR4 1TB NVMe Windows 11 Home

Compact desktop for everyday tasks

The Acer Aspire XC-840-UB11 is a small-form-factor desktop built around an Intel Celeron N4505 processor and Intel UHD Graphics. It ships with 16GB of DDR4 memory and a 1TB PCIe NVMe SSD, running Windows 11 Home. The system suits home offices, education settings or light business workloads that rely on web apps and document editing. It is not aimed at buyers who need discrete graphics performance or multi-threaded rendering power.

Thermals and power in daily use

A 65-watt power supply feeds the low-power CPU and integrated graphics, keeping heat output modest during typical office loads. The compact chassis measures 12.99 x 3.94 x 11.61 inches and weighs 9.26 pounds, allowing it to sit on a desk or be mounted out of sight. Fan noise stays low during web browsing and video playback. The platform supports up to 32GB of DDR4 if future workloads demand more memory headroom.

Included accessories and connectivity

A wired keyboard and mouse combo are bundled so the PC is ready to use straight from the box. Wireless connectivity comes from an Intel Wi-Fi 6 (2x2) module paired with Bluetooth 5.3 for peripherals and mobile devices. No display is included, so buyers must provide their own monitor. The Windows 11 Home licence activates on first boot for immediate access to the OS and store apps.
