Acer Aspire C27 Professional All-in-One PC 27" 120Hz Core 5 120U 16GB DDR5 4TB NVMe Win 11 Home

What this all-in-one does

The Acer Aspire C27 Professional is a 27-inch all-in-one desktop built around a 15th Gen Intel Core 5 120U processor with ten cores and twelve threads. It ships with 16GB of DDR5 memory and a 4TB PCIe NVMe SSD, running Windows 11 Home. The integrated IPS panel runs at 1920x1080 resolution with a 120Hz refresh rate. Connectivity includes Wi-Fi 6E, Bluetooth 5.3, RJ-45, HDMI, DisplayPort and USB 3.2 Type-C.

Storage capacity and type

The single specification that decides fit is the 4TB PCIe NVMe solid-state drive. That capacity and interface determine whether the machine can hold the project libraries, media caches or virtual-machine images the buyer works with every day. No mechanical hard drive is present, so latency-sensitive workloads benefit from consistent SSD access speeds. The drive is not user-replaceable without opening the sealed chassis.

Sustained workload behaviour

Under continuous load the 65-watt power supply limits the processor to its base power envelope, so clock speeds settle below the 5 GHz single-core maximum. The integrated graphics share system memory, so extended render or compute tasks compete with the 16GB DDR5 pool for bandwidth. Thermal throttling can appear during multi-hour compile or export sessions because the all-in-one form factor restricts airflow compared with a tower chassis.
