Desktop for home and office

The Acer Aspire TC-1775-UR11 is a compact tower built around a 14th Gen Intel Core i5-14400 processor with ten cores and sixteen threads. It ships with 16GB of DDR5 memory, a 1TB PCIe NVMe SSD paired with a 3TB hard drive, and Windows 11 Pro. Integrated Intel UHD Graphics 730 handles display output through two HDMI ports.

Thermals noise and 300W supply

A 300-watt power supply feeds the CPU, memory, storage and an air cooler in a chassis measuring 6.7 by 13.9 by 13.45 inches. Wi-Fi 6E AX211 and Bluetooth 5.3 add wireless connectivity without extra antennas. Under typical office workloads the system runs quietly, drawing only a fraction of the supply’s rated capacity.

Sustained load behaviour

When all ten cores run near their 4.7 GHz maximum turbo the air cooler must dissipate the processor’s full heat output within the same 300-watt envelope. The single 3.5-inch hard drive adds mechanical latency during long write sequences, while the NVMe drive maintains its throughput. Buyers who need discrete graphics headroom or a higher-wattage supply for expansion should look elsewhere.

Questions about this item

How do I add a second DDR5 DIMM to the two-slot motherboard without bending the pins?

Open the chassis, line up the single notch on the DDR5 module with the slot key, press straight down until both retention clips snap shut, then confirm the new total in BIOS.

Which drive will need attention first — the 1TB NVMe SSD or the 3TB 3.5-inch HDD?

The 3TB hard drive has moving parts and will likely require replacement before the solid-state drive; keep backups current.

What thermal ceiling appears first when the i5-14400 runs at 4.7 GHz on the stock 300W supply and air cooler?

The 300 watt power budget and the included air cooler limit sustained turbo clocks before the CPU hits its own thermal maximum.
