Acer America Aspire XC-840-UB11 desktop PC, Intel Celeron N4505, 8 GB DDR4, 512 GB NVMe, Windows 11 Home

Compact desktop for everyday tasks

The Acer Aspire XC-840-UB11 is a small-form-factor PC built around an Intel Celeron N4505 processor with Intel UHD Graphics, 8 GB of DDR4 memory and a 512 GB NVMe solid-state drive. It ships with Windows 11 Home and includes a wired keyboard and mouse. The system is aimed at home or office users who need a quiet, space-saving machine for web browsing, document work and video playback.

Check power and expansion needs

The unit uses a 65-watt power supply, so any added components must stay within that budget. Internal space is limited by the 12.99 x 3.94 x 11.61-inch chassis, which restricts full-height cards and larger coolers. Memory can be expanded up to 32 GB of DDR4, and the M.2 slot supports up to 1 TB of NVMe storage. Verify that your peripherals and monitors match the available video outputs before ordering.

Included peripherals and connectivity

The bundled wired keyboard and mouse let you start working immediately without buying separate input devices. Wireless connectivity comes from Wi-Fi 6 and Bluetooth 5.3, providing modern speeds for compatible routers and accessories. No display is included, so you will need to supply your own monitor or TV.
