Acer Aspire TC-1775-UR11 desktop PC i5-14400 8GB DDR5 512GB NVMe + 3TB HDD Win 11 Pro

14th Gen Core i5 desktop for office work

The Acer Aspire TC-1775-UR11 pairs a 10-core i5-14400 processor with 8GB of DDR5 memory at 4800MHz. It runs Windows 11 Pro on a 512GB NVMe SSD and adds a 3TB hard drive for bulk storage. Integrated Intel UHD 730 graphics drive two HDMI outputs and a USB 3.2 Type-C port. Wi-Fi 6E and Bluetooth 5.3 handle wireless duties.

Sustained load on the 300W supply

The 300W power supply feeds the CPU up to its 4.7GHz turbo across six performance cores. Air cooling keeps the 20MB L3 cache fed during long compile or spreadsheet sessions. The single 8GB DIMM leaves one slot open for a future memory upgrade. Integrated graphics share system memory, so heavy multitasking will reduce bandwidth available to the CPU.

Thermals noise and power in daily use

The compact 6.7 by 13.9 by 13.45 inch chassis uses an air cooler that stays quiet during typical office loads. At 10.2lb the unit is easy to reposition on a desk. The 300W supply draws modest wall power while the SSD handles OS and apps without mechanical noise. The 3.5 inch hard drive spins only when large archives are accessed.
