Features

VESA Mount Function

The VESA mount allows you to attach the mini PC to the back of a monitor or TV, saving desk space and creating a cleaner setup. This is especially useful in small offices or home environments where space is limited, providing a tidy and organized workspace.

Dual Display Output Function

The multiple display outputs, including HDMI, DisplayPort, and Thunderbolt 4, enable you to connect up to four monitors simultaneously, enhancing productivity and multitasking capabilities. This is ideal for users who need to work with multiple applications at once or require extended screen real estate.

Expandable Storage Function

The TOPGRO K3 Mini PC has 2x M.2 2280 SSD slots, expandable up to 8TB, providing flexibility to increase storage capacity as needed. Suitable for users who require more space for files, applications, and media, ensuring long-term usability and scalability.

External USB Boot Function

The ability to boot from an external USB drive makes it easy to install different operating systems or perform system recovery. This is a convenient feature for troubleshooting and customization, allowing users to easily manage and maintain their system without needing specialized tools.

Kensington Lock Function

The Kensington lock function is not mentioned in the product information, so it is assumed that it is not available. This might be a drawback for users who require physical security for their device in public or shared environments, potentially increasing the risk of theft.

Fanless Cooling Function

The fanless design ensures silent operation, eliminating noise from a cooling fan. This function is beneficial for users who require a quiet working environment, such as in a home office or media center, creating a more peaceful and distraction-free experience, although thermal performance should be monitored.
